WSA881x works in PDM mode so the wordlength is fixed, which also makes
the only field "WordLength" in DPN_BlockCtrl1 register a read-only.
Writing to this register will throw up errors with Qualcomm Controller.
So use ro_blockctrl1_reg flag to mark this field as read-only so that
core will not write to this register.

On some Lenovo and HP laptops, if both codec driver and SOF driver
are in runtime suspend mode, we plug a headset to the audio jack,
the headphone could be detected but Mic couldn't.
That is because when plugging, the headphone triggers a unsol event
first, and about 0.7s later (on the Lenovo X1 Carbon 7th), the Mic
triggers a unsol event. But if the codec driver enters runtime suspend
within 0.7s, the Mic can't trigger the unsol event.
If we don't set autosuspend_delay to a non-zero value for the hda codec
driver, it will enter runtime suspend immediately after the headphone
triggers the unsol event.
Follow the sequence of legacy hda driver and set a autosuspend delay
of 1sec after card registration (refer to pci/hda/hda_intel.c and
pci/hda/hda_codec.c).

Refactoring was done to factor out the linking of DAI widgets into
a helper function, dapm_add_valid_dai_widget. However when this was
done, a regression was introduced for CODEC to CODEC links. It was
over looked that the playback and capture variables persisted across
all CODEC DAIs being processed, which ensured that the special DAI
widget that is added for CODEC to CODEC links was only created once.
This bug causes kernel panics during DAPM shutdown.
To stick with the spirit of the original refactoring whilst fixing the
issue, variables to hold the DAI widgets are added to snd_soc_dai_link.
Furthermore the dapm_add_valid_dai_widget function is renamed to
dapm_connect_dai_pair, the function only adds DAI widgets in the CODEC
to CODEC case and its primary job is to add routes connecting two DAI
widgets, making the original name quite misleading.

Commit 450312b640 ("ASoC: soc-core: remove DAI suspend/resume")
removed the DAI side suspend/resume hooks and switched entirely to
component suspend/resume. However the Samsung SoC s3c-i2s-v2 driver was
not updated.
Move the suspend/resume hooks from s3c-i2s-v2.c to s3c2412-i2s.c while
changing dai to component which allows to keep the struct
snd_soc_component_driver const.
This fixes build errors:

They are all supposed to be sorted, but people who add new entries don't
always know the alphabet. Plus sometimes the entry names get edited,
and people don't then re-order the entry.
Let's see how painful this will be for merging purposes (the MAINTAINERS
file is often edited in various different trees), but Joe claims there's
relatively few patches in -next that touch this, and doing it just
before -rc1 is likely the best time. Fingers crossed.
This was scripted with
/scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS
but then I also ended up manually upper-casing a few entry names that
stood out when looking at the end result.

detection feature.
It addressed the case where a KVM guest triggers a split lock #AC and KVM
reinjects it into the guest which is not prepared to handle it.
Adds proper sanity checks which prevent the unconditional injection into
the guest and handles the #AC on the host side in the same way as user
space detections are handled. Depending on the detection mode it either
warns and disables detection for the task or kills the task if the mode is
set to fatal.

"A set of three patches to fix the fallout of the newly added split
lock detection feature.
It addressed the case where a KVM guest triggers a split lock #AC and
KVM reinjects it into the guest which is not prepared to handle it.
Add proper sanity checks which prevent the unconditional injection
into the guest and handles the #AC on the host side in the same way as
user space detections are handled. Depending on the detection mode it

KVM: VMX: Extend VMXs #AC interceptor to handle split lock #AC in guest
KVM: x86: Emulate split-lock access as a write in emulator
x86/split_lock: Provide handle_guest_split_lock()
- Fix the time_for_children symlink in /proc/$PID/ so it properly reflects
that it part of the 'time' namespace
- Add the missing userns limit for the allowed number of time namespaces,
which was half defined but the actual array member was not added. This
went unnoticed as the array has an exessive empty member at the end but
introduced a user visible regression as the output was corrupted.
- Prevent further silent ucount corruption by adding a BUILD_BUG_ON() to
catch half updated data.
