For avoiding the potential deadlock via kill_fasync() call, use the
new fasync helpers to defer the invocation from the control API. Note
that it's merely a workaround.
Another note: although we haven't received reports about the deadlock
with the control API, the deadlock is still potentially possible, and
it's better to align the behavior with other core APIs (PCM and
timer); so let's move altogether.

Currently the call of kill_fasync() from an interrupt handler might
lead to potential spin deadlocks, as spotted by syzkaller.
Unfortunately, it's not so trivial to fix this lock chain as it's
involved with the tasklist_lock that is touched in allover places.
As a temporary workaround, this patch provides the way to defer the
async signal notification in a work. The new helper functions,
snd_fasync_helper() and snd_kill_faync() are replacements for
fasync_helper() and kill_fasync(), respectively. In addition,
snd_fasync_free() needs to be called at the destructor of the relevant
file object.

Historically, the legacy DAI naming scheme was applied to platform
drivers and the newer scheme to CODEC drivers. During componentisation
the core lost the knowledge of if a driver was a CODEC or platform, they
were all now components. To continue to support the legacy naming on
older platform drivers a flag was added to the snd_soc_component_driver
structure, non_legacy_dai_naming, to indicate to use the new scheme and
this was applied to all CODECs as part of the migration.
However, a slight issue appears to be developing with respect to this
flag being opt in for the non-legacy scheme, which presumably we want to
be the primary scheme used. Many codec drivers appear to forget to
include this flag:
grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c |
xargs grep -L "non_legacy_dai_naming" | wc
48 48 556
It would seem more sensible to change the flag to legacy_dai_naming
making the new scheme opt out. As a first step this patch adds a new
flag for this so that the users can be updated.

The control elements are managed in a single linked list and we
traverse the whole list for matching each numid or ctl id per every
inquiry of a control element. This is OK-ish for a small number of
elements but obviously it doesn't scale. Especially the matching with
the ctl id takes time because it checks each field of the snd_ctl_id
element, e.g. the name string is matched with strcmp().
This patch adds the hash tables with Xarray for improving the lookup
speed of a control element. There are two xarray tables added to the
card; one for numid and another for ctl id. For the numid, we use the
numid as the index, while for the ctl id, we calculate a hash key.
The lookup is done via a single xa_load() execution. As long as the
given control element is found on the Xarray table, that's fine, we
can give back a quick lookup result. The problem is when no entry
hits on the table, and for this case, we have a slight optimization.
Namely, the driver checks whether we had a collision on Xarray table,
and do a fallback search (linear lookup of the full entries) only if a
hash key collision happened beforehand.
So, in theory, the inquiry for a non-existing element might take still
time even with this patch in a worst case, but this must be pretty
rare.
The feature is enabled via CONFIG_SND_CTL_FAST_LOOKUP, which is turned
on as default. For simplicity, the option can be turned off only when
CONFIG_EXPERT is set ("You are expert? Then you manage 1000 knobs").

This set of patches includes changes to add the topology, control and

As part of retiring the old defines used to specify DAI formats update the
hdmi_codec driver to use the modern names, including the variables in the
struct hdmi_codec_daifmt exported to the DRM drivers.
In updating this I did note that the only use of this information in DRM
drivers is to reject clock provider settings, thinking about what this
hardware is doing I rather suspect that there might not be any hardware
out there which needs the configuration so it may be worth considering
just having hdmi-codec support only clock consumer.

Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:
Currently the set_fmt callback always passes clock provider/consumer
with respect to the CODEC. This made sense when the framework was
directly broken down into platforms and CODECs. However, as things
are now broken down into components which can be connected as either
the CPU or CODEC side of a DAI link it simplifies things if each
side of the link is just told if it is provider or consumer of the
clocks. Making this change allows us to remove one of the last parts
of the ASoC core that needs to know if a driver is a CODEC driver,
where it flips the clock format specifier if a CODEC driver is used on
the CPU side of a DAI link, as well as just being conceptually more
consistent with componentisation.
The basic idea of this patch chain is to change the set_fmt callback
from specifying if the CODEC is provider/consumer into directly
specifying if the component is provider/consumer. To do this we add
some new defines, and then to preserve bisectability, the migration is
done by adding a new callback, converting over all existing CPU side
drivers, converting the core, and then finally reverting back to the
old callback.
Converting the platform drivers makes sense as the existing defines
are from the perspective of the CODEC and there are more CODEC drivers
than platform drivers.
Obviously a fair amount of this patch chain I was only able to build
test, so any testing that can be done would be greatly appreciated.
asoc_simple_clean_reference() returns zero unconditionally. Letting it
return void instead makes it easier to see in the caller that there is no
error to handle.

From there on is a range of boards appended. All of them follow the same:
This series focuses on populating boards/ subdirectory with supported
configurations by the avs-driver. Note: it is independent of recently
provided "Driver code and PCM operations" series [1], that is, code
found here should not collide with it.
Series starts with a small change that adds a helper to sound pcm
header, allowing for retrieving string naming a direction without the
need of substream pointer. Said helper is used by codec driver code that
follows it but I believe it's generic and helpful enough that it can be
called an independent addition to the sound core.
Code for generic HD-Audio codec driver follows. It is a ASoC wrapper for
existing HD-Audio codec code found in sound/pci/hda/. There is basically
no custom logic involved up to the point that driver follows
HDA_DEV_LEGACY convention, rather than the HDA_DEV_ASOC one. Commit
message for the given patch iterates on this and explains crucial parts
of the implementation.
From there on is a range of boards appended. All of them follow the same
scheme:
- define avs_create_dai_link() so DAI-LINKs can be created dynamically,
based on the link_mask (I2S) or the number of entries in the
->pcm_list_head list (HDA)
- define avs_create_dapm_routes() so DAPM routes can be created
dynamically, same rules as above apply
- define probe() function that creates new ASoC card, assign all
required operations and resources along with calling the two above
Changes in v2:
- 'link_mask' usage replaced with 'i2s_link_mask' as requested by
Pierre
- 'ssp_test' board renamed to 'i2s_test' to match naming convention used
for other i2s machine boards
- enriched commit message and Kconfig for the 'HD-Audio codec driver'

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
Small updates to add initial tables for MeteorLake, SoundWire machine
driver support for tests without HDMI and RT1019 for consistency on
Chromebooks.
Since the CS35L41 HDA driver also support hibernation, it
makes sense to move code from the ASoC driver to enter
hibernation into common code.
Since HDA must support laptops which do not support hibernation
due to lack of external boost GPIO it is necessary to
ensure the function returns an error when an unsupported
boost type is in use.

The helper function snd_soc_component_is_codec is based off the
presence of the non_legacy_dai_naming flag. This isn't super robust
as CPU side components may also specify this flag, and indeed the
kernel already contains a couple that do. After componentisation there
isn't really a totally robust solution to identifying what is a CODEC
driver, without introducing a flag specifically for that purpose, and
really the desirable direction to move in is that the distinction
doesn't matter.
This patch does two things to try to mitigate these problems. Firstly,
now that all the other users of the helper function have been removed,
it makes the helper function local to the driver rather, than being
part of the core. This should help to discourage any new code from
being created that depends on the CODEC driver distinction. Secondly,
it updates the helper function itself to use the endianness flag
rather than the non_legacy_dai_naming flag. The endianness flag is
definitely invalid on a CPU side component, so it a more reliable
indicator that the device is definitely a CODEC. The vast majority of
buses require the CODEC to set the endianness flag, so the number of
corner cases should be fairly minimal. It is worth noting that CODECs
sending audio over SPI, or built into the CPU CODECs are potential
corner cases, however the hope is that in most cases those types of
devices do not consitute a simple audio card.

The original set_fmt callback always passes clock provider/consumer
with respect to the CODEC. This made sense when the framework was
directly broken down into platforms and CODECs. Now everything is
componentised it simplifies things if each side of the link is
just told if it is provider or consumer of the clocks. To start
this migration add a new callback that can be used to receive a
direct specification of clocking. As there are more CODEC drivers
than platform drivers, we make the new flags identical to the old
CODEC flags meaning CODEC drivers will not require an update.

The second part of the multiplatform changes now converts the
Intel/Marvell PXA platform along with the rest. The patches went through
several rebases before the merge window as bugs were found, so they
remained separate.
This has to touch a lot of drivers, in particular the touchscreen,
pcmcia, sound and clk bits, to detach the driver files from the
platform and board specific header files.

The host stream position is updated when no_stream_position is set as 0.
However current implementation updates host stream position only when
report data is larger than or equal to host period size which is decided
by the period size of host side. It maybe cause host stream position
update not in time. Therefore this patch introduces another field
"cont_update_posn", a boolean value aimed to update host stream position
continuously and based on period size of pipeline. It can get better
precise when need to update host stream position from firmware.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
With additional tests with the introduction of a 'deep-buffer' PCM
device mixed with the regular low-latency path, we came up with two
improvements in the BE state machine and transitions. The short
explanation is that the BE cannot directly use the trigger commands
provided by the FE, and a translation is needed to deal with paused
states.
Commit 3aa1e96a2b ("ASoC: soc-pcm: fix BE handling of PAUSE_RELEASE")
did not modify the existing logic and kept the same logic for the following
transition
play FE1 -> BE state is START
pause FE1 -> BE state is PAUSED
play FE2 -> BE state is START
stop FE2 -> BE state is STOP <<< !!
release FE1 -> BE state is START
stop FE1 -> BE state is STOP
At the time it was identified by reviewers that a better solution
might consist in
play FE1 -> BE state is START
pause FE1 -> BE state is PAUSED
play FE2 -> BE state is START
stop FE2 -> BE state is PAUSE <<< !!
release FE1 -> BE state is START
stop FE1 -> BE state is STOP
This patch suggest a transition to PAUSE when all the 'active' streams
are paused. This would allow for a more consistent resource management
for platforms where PAUSE and STOP are handled differently.
To track the special case of an FE going from PAUSE_PUSH to STOP, we
add a state variable for each FE context. This 'fe_pause' boolean is
set on PAUSE_PUSH and cleared on either PAUSE_RELEASE and STOP
triggers.

A collection of fixes that came in since the merge window, plus one new
device ID for an x86 laptop. Nothing that really stands out with
particularly big impact outside of the affected device.
Now that we start having multiple platforms with minor variants, the
use of the const qualifier for 'dsp_ops' is starting to be
sub-optimal: the structures are copied across platforms, with only a
couple of members that differ.
This patch removes the const qualifier without any functionality
changes, and adds an optional initialization callback. In follow-up
patches, the dsp_ops will revisited for Intel HDaudio platforms, with
the differences added programmatically over a common baseline.

snd_soc_card_jack_new() allowed to create jack kcontrol without pins,
but did not create kcontrols. The jack would not have kcontrols if pins
were not going to be added.
This renames the old snd_soc_card_jack_new() to
snd_soc_card_jack_new_pins() for use when pins are provided or will be
added later. The new snd_soc_card_jack_new() appropriately creates a
jack for use without pins and adds a kcontrol.

The recent change for memory allocator replaced the SG-buffer handling
helper for x86 with the standard non-contiguous page handler. This
works for most cases, but there is a corner case I obviously
overlooked, namely, the fallback of non-contiguous handler without
IOMMU. When the system runs without IOMMU, the core handler tries to
use the continuous pages with a single SGL entry. It works nicely for
most cases, but when the system memory gets fragmented, the large
allocation may fail frequently.
Ideally the non-contig handler could deal with the proper SG pages,
it's cumbersome to extend for now. As a workaround, here we add new
types for (minimalistic) SG allocations, instead, so that the
allocator falls back to those types automatically when the allocation
with the standard API failed.
BTW, one better (but pretty minor) improvement from the previous
SG-buffer code is that this provides the proper mmap support without
the PCM's page fault handling.

This is a small helper function to handle the error path more easily
when an error happens during the probe for the device with the
device-managed card. Since devres releases in the reverser order of
the creations, usually snd_card_free() gets called at the last in the
probe error path unless it already reached snd_card_register() calls.
Due to this nature, when a driver expects the resource releases in
card->private_free, this might be called too lately.
As a workaround, one should call the probe like:
static int __some_probe(...) { // do real probe.... }
static int some_probe(...)
{
return snd_card_free_on_error(dev, __some_probe(dev, ...));
}
so that the snd_card_free() is called explicitly at the beginning of
the error path from the probe.
This function will be used in the upcoming fixes to address the
regressions by devres usages.

HDA Jack detection logic doesn't work when the HDACODEC
in runtime suspended state as unsol event won't be triggered
during D3 state. As pulseaudio server in userspace rely on the
jack mixer control status to show the audio devices in gui and
any display sink device hotplug event during D3 state will never
updates the jack status which will result in no audio device option
available in userspace settings.
The possible option available to resolve this issue is to run Jack
polling worker thread even after codec suspend state. The choice can
be made based on compromise between power saving or Jack detection in
suspend state.

Add a helper function snd_soc_tdm_params_to_bclk() to calculate
the bclk from params info and the tdm sots configuration.
When using a TDM frame of N slots of width W bits:
bclk = sample_rate * N * W
As a convenience to simplify calling code, if the slot count or
slot width are 0 a value will be obtained from the params. This
allows calling code to use this one function to handle cases of
TDM where only one parameter is fixed, or I2S where the slot width
is fixed (for example to set a 32-bit slot for 24-bit samples).
Also as a convenience the slot count can optionally be rounded up
to a multiple. This is mainly useful for I2S systems, since I2S has
two phases of LRCLK the number of slots is always a multiple of 2.

syzbot caught a potential deadlock between the PCM
runtime->buffer_mutex and the mm->mmap_lock. It was brought by the
recent fix to cover the racy read/write and other ioctls, and in that
commit, I overlooked a (hopefully only) corner case that may take the
revert lock, namely, the OSS mmap. The OSS mmap operation
exceptionally allows to re-configure the parameters inside the OSS
mmap syscall, where mm->mmap_mutex is already held. Meanwhile, the
copy_from/to_user calls at read/write operations also take the
mm->mmap_lock internally, hence it may lead to a AB/BA deadlock.
A similar problem was already seen in the past and we fixed it with a
refcount (in commit b248371628). The former fix covered only the
call paths with OSS read/write and OSS ioctls, while we need to cover
the concurrent access via both ALSA and OSS APIs now.
This patch addresses the problem above by replacing the buffer_mutex
lock in the read/write operations with a refcount similar as we've
used for OSS. The new field, runtime->buffer_accessing, keeps the
number of concurrent read/write operations. Unlike the former
buffer_mutex protection, this protects only around the
copy_from/to_user() calls; the other codes are basically protected by
the PCM stream lock. The refcount can be a negative, meaning blocked
by the ioctls. If a negative value is seen, the read/write aborts
with -EBUSY. In the ioctl side, OTOH, they check this refcount, too,
and set to a negative value for blocking unless it's already being
accessed.

Currently we have neither proper check nor protection against the
concurrent calls of PCM hw_params and hw_free ioctls, which may result
in a UAF. Since the existing PCM stream lock can't be used for
protecting the whole ioctl operations, we need a new mutex to protect
those racy calls.
This patch introduced a new mutex, runtime->buffer_mutex, and applies
it to both hw_params and hw_free ioctl code paths. Along with it, the
both functions are slightly modified (the mmap_count check is moved
into the state-check block) for code simplicity.

In preparation for adding support for the new IPC version that has been
introduced in the SOF firmware, this patch set includes some clean ups
and necessary modifications to commonly used functions that will be
re-used across different IPC-specific code.
Different topology filenames may be required depending on which SSP is
used, and whether or not digital mics are present.
This patch adds a tplg_quirk_mask and in the case of the SOF driver
adds the relevant configurations.
This is a short-term solution to the ES8336 support issues.
In a long-term solution, we would need an interface where the machine
driver or platform driver have the ability to alter the topology
hard-coded low-level hardware support, e.g. by substituting an
interface for another, or disabling an interface that is not supported
on a given skew.

The NHLT information can be used to figure out which SSPs are enabled
in a platform.
The 'SSP' link type is too broad for machine drivers, since it can
cover the Bluetooth sideband and the analog audio codec connections,
so this helper exposes a parameter to filter with the device
type (DEVICE_I2S refers to analog audio codec in NHLT parlance).
The helper returns a mask, since more than one SSP may be used for
analog audio, e.g. the NHLT spec describes the use of SSP0 for
amplifiers and SSP1 for headset codec. Note that if more than one bit
is set, it's impossible to determine which SSP is connected to what
external component. Additional platform-specific information based on
e.g. DMI quirks would still be required in the machine driver to
configure the relevant dailinks.

Some audio hardware cannot support the same slot width for all sample
widths, or a slot width equal to the sample width for all sample widths.
This is usually due either to limitations of the audio serial port or
system clocking restrictions.
A typical example would be:
- 16-bit samples in 16-bit slots
- 24-bit samples in 32-bit slots
The new dai-tdm-slot-width-map property allows setting a mapping of
sample widths and the corresponding tdm slot widths and slot counts.
Although the slot count is usually the same for all cases this does
allow for adding padding slots to maintain the same bitclk frequency.
The property is added to each endpoint node that needs the component
DAI to be told the TDM slot width and count.

having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
This code was transformed with the help of Coccinelle:

ASoC: Fixes for v5.17
Quite a few fixes here, including an unusually large set in the core
spurred on by various testing efforts as well as the usual small driver
fixes. There are quite a few fixes for out of bounds writes in both the
core and the various Qualcomm drivers, plus a couple of fixes for
locking in the DPCM code.
The recent change for DPCM locking caused spurious lockdep warnings.
Actually the warnings are false-positive, as those are triggered due
to the nested stream locks for FE and BE. Since both locks belong to
the same lock class, lockdep sees it as if a deadlock.
For fixing this, we need to take PCM stream locks for BE with the
nested lock primitives. Since currently snd_pcm_stream_lock*() helper
assumes only the top-level single locking, a new helper function
snd_pcm_stream_lock_irqsave_nested() is defined for a single-depth
nested lock, which is now used in the BE DAI trigger that is always
performed inside a FE stream lock.
Fixes: b2ae806630 ("ASoC: soc-pcm: serialize BE triggers")

Merge series from Robert Hancock <robert.hancock@calian.com>:
There are drivers in mainline for the Xilinx Audio Formatter and Xilinx
I2S IP cores. However, because of a few issues, these were only really
usable with Xilinx's xlnx_pl_snd_card top-level driver, which is not in
mainline (and not suitable for mainline).
The fixes in this patchset, for the simple-card layer as well as the
Xilinx drivers, now allow these drivers to be properly used with
simple-card without any out-of-tree support code.
Add a new system-clock-fixed flag, which can be used to specify that the
driver cannot or should not allow the clock frequency of the mapped clock
to be modified. This behavior is also implied if the system-clock-frequency
parameter is set explicitly - the flag is meant for cases where a clock is
mapped to the DAI but which is, or should be treated as, fixed.
When mclk-fs is also specified, this causes a PCM constraint to be added
which enforces that only the corresponding valid sample rate can be used.

The HDAudio ASoC support relies on the set_tdm_slots() helper to store
the HDaudio stream tag in the tx_mask. This only works because of the
pre-existing order in soc-pcm.c, where the hw_params() is handled for
codec_dais *before* cpu_dais. When the order is reversed, the
stream_tag is used as a mask in the codec fixup functions:
/* fixup params based on TDM slot masks */
if (substream->stream == SNDRV_PCM_STREAM_PLAYBACK &&
codec_dai->tx_mask)
soc_pcm_codec_params_fixup(&codec_params,
codec_dai->tx_mask);
As a result of this confusion, the codec_params_fixup() ends-up
generating bad channel masks, depending on what stream_tag was
allocated.
We could add a flag to state that the tx_mask is really not a mask,
but it would be quite ugly to persist in overloading concepts.
Instead, this patch suggests a more generic get/set 'stream' API based
on the existing model for SoundWire. We can expand the concept to
store 'stream' opaque information that is specific to different DAI
types. In the case of HDAudio DAIs, we only need to store a stream tag
as an unsigned char pointer. The TDM rx_ and tx_masks should really
only be used to store masks.
Rename get_sdw_stream/set_sdw_stream callbacks and helpers as
get_stream/set_stream. No functionality change beyond the rename.

Merge series from Dmitry Osipenko <digetx@gmail.com>:
This series revives Tegra20 S/PDIF driver which was upstreamed long time
ago, but never was used. It also turns Tegra DRM HDMI driver into HDMI
audio CODEC provider. Finally, HDMI audio is enabled in device-trees.
For now the audio is enable only for Acer A500 tablet and Toshiba AC100
netbook because they're already supported by upstream, later on ASUS TF101
tablet will join them.
I based S/PDIF patches on Arnd's Bergmann patch from a separate series [1]
that removes obsolete slave_id. This eases merging of the patches by
removing the merge conflict. This is a note for Mark Brown.
I also based this series on top of power management series [2]. I.e. [2]
should be applied first, otherwise "Add S/PDIF node to Tegra20 device-tree"
patch should have merge conflict. This is a note for Thierry.

[2] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=274534
Changelog:
v4: - Added patches that update multi_v7_defconfig with the enabled S/PDIF
and APB DMA drivers.
v3: - Renamed S/PDIF device-tree clocks as was suggested by Rob Herring.
- Added r-bs and acks that were given by Rob Herring to v2.
v2: - Corrected I2S yaml problem that was reported by the DT bot for v1
by removing the non-existent required clock-names property.
- Removed assigned-clocks property from S/PDIF yaml since this property
is now inherited from the clocks property.
- Reordered the "tegra20: spdif: Set FIFO trigger level" patch, making
it the first sound/soc patch in the series, like it was suggested by
Mark Brown in the comment to v1. Also reworded commit message of this
patch to *not* make it looks like it should be backported to stable
kernels.

On start/pause_release/resume, when more than one FE is connected to
the same BE, it's possible that the trigger is sent more than
once. This is not desirable, we only want to trigger a BE once, which
is straightforward to implement with a refcount.
For stop/pause/suspend, the problem is more complicated: the check
implemented in snd_soc_dpcm_can_be_free_stop() may fail due to a
conceptual deadlock when we trigger the BE before the FE. In this
case, the FE states have not yet changed, so there are corner cases
where the TRIGGER_STOP is never sent - the dual case of start where
multiple triggers might be sent.
This patch suggests an unconditional trigger in all cases, without
checking the FE states, using a refcount protected by the BE PCM
stream lock.

The existing locking for DPCM has several issues
a) a confusing mix of card->mutex and card->pcm_mutex.
b) a dpcm_lock spinlock added inconsistently and on paths that could
be recursively taken. The use of irqsave/irqrestore was also overkill.
The suggested model is:
1) The pcm_mutex is the top-most protection of BE links in the FE. The
pcm_mutex is applied always on either the top PCM callbacks or the
external call from DAPM, not taken in the internal functions.
2) the FE stream lock is taken in higher levels before invoking
dpcm_be_dai_trigger()
3) when adding and deleting a BE, both the pcm_mutex and FE stream
lock are taken.

Regarding to handling [U|S][32|24] PCM formats, many userspace
application developers and driver developers have confusion, since they
require them to understand justification or padding. It easily
loses consistency and soundness to operate with many type of devices. In
this commit, I attempt to solve the situation by adding comment about
relation between [S|U]32 formats and 'msbits' hardware parameter.
The formats are used for 'left-justified' sample format, and the available
bit count in most significant bit is delivered to userspace in msbits
hardware parameter (struct snd_pcm_hw_params.msbits), which is decided by
msbits constraint added by pcm drivers (snd_pcm_hw_constraint_msbits()).
In driver side, the msbits constraint includes two elements; the physical
width of format and the available width of the format in most significant
bit. The former is used to match SAMPLE_BITS of format. (For my
convenience, I ignore wildcard in the usage of the constraint.)
As a result of interaction between ALSA pcm core and ALSA pcm application,
when the format in which SAMPLE_BITS equals to physical width of the
msbits constaint, the msbits parameter is set by referring to the
available width of the constraint. When the msbits parameter is not
changed in the above process, ALSA pcm core set it alternatively with
SAMPLE_BIT of chosen format.
In userspace application side, the msbits is only available after calling
ioctl(2) with SNDRV_PCM_IOCTL_HW_PARAMS request. Even if the hardware
parameter structure includes somewhat value of SAMPLE_BITS interval
parameter as width of format, all of the width is not always available
since msbits can be less than the width.
I note that [S|U]24 formats are used for 'right-justified' 24 bit sample
formats within 32 bit frame. The first byte in most significant bit
should be invalidated. Although the msbits exposed to userspace should be
zero as invalid value, actually it is 32 from physical width of format.
