Currently we bail out when the device returns an error or an invalid
value for the current clock selector value via
uac_clock_selector_get_val(). But it's possible that the device is
really uninitialized and waits for the setup of the proper route at
first.
For handling such a case, this patch lets the driver dealing with the
error or the invalid error more gracefully, choosing the clock source
automatically instead.

This patch just does refactoring of the UAC2/3 clock setup code.
There should be no functional changes. The major changes are:
* Provide union objects for pointing both UAC2 and UAC3 objects
* Unify clock source, selector and multiplier helper functions
* Unify __uac_clock_find_source() to deal with both UAC2 and UAC3
equally

The array bounds check on clock_names is currently checking the size
of the entire array rather than the number of elements in the array
leading to a potential array bounds read error. Fix this by using

ALSA OXFW supports two types of ASICS; OXFW970 and OXFW971. The former
is known to have a quirk we call 'jumbo payload' that some isochronous
cycles are skipped to transfer isochronous packets during handling
asynchronous transaction. The quirk seems to correspond to firmware
initially delivered by Oxford Semiconductor since the quirk is not
confirmed for Mackie Onyx Satellite in which the revised firmware is
available. The quirk is not confirmed in the latter.
This commit adds code comment to describe the quirk.

'Mackie DJ Mixer' in its model name of configuration ROM. On the other
hand, built-in FireWire card for d.2 Pro and d.4 Pro uses OXFW971 ASIC
and has 'd.Pro' in its model name according to manuals and user

Theoretically the initialization functions in usx2y drivers may be
called multiple times as the driver gets initialized via hwpdep
ioctl. Meanwhile, those functions including memory allocations don't
check whether they are called twice, and they forget the old
resources, which would lead to memory leaks.
This patch adds the sanity checks about the doubly initializations to
give kernel WARNING, and returns an error in such a case. Also, each
allocation assures to release the resources at its error path
properly.

The initialization os usx2y driver is multi-staged, and the PCM and
other device creations are done after the DSP is loaded and
initialized. Upon the initialization, when an error happens, the
driver tries to call snd_card_free(). But this is dangerous, and in
general, the driver cannot kill itself during its operation.
Hence better to drop the snd_card_free() call from there.

This commit adds a new framing mode that frames all MIDI data into
32-byte frames with a timestamp.
The main benefit is that we can get accurate timestamps even if
userspace wakeup and processing is not immediate.
Testing on a Celeron N3150 with this mode has a max jitter of 2.8 ms,
compared to the in-kernel seq implementation which has a max jitter
of 5 ms during idle and much worse when running scheduler stress tests
in parallel.

The interrupt handler of intel8x0 calls snd_intel8x0_update() whenever
the hardware sets the corresponding status bit for each stream. This
works fine for most cases as long as the hardware behaves properly.
But when the hardware gives a wrong bit set, this leads to a zero-
division Oops, and reportedly, this seems what happened on a VM.
For fixing the crash, this patch adds a internal flag indicating that
the stream is ready to be updated, and check it (as well as the flag
being in suspended) to ignore such spurious update.

"Three small SMB3 chmultichannel related changesets (also for stable)
from the SMB3 test event this week.
The other fixes are still in review/testing"
* tag '5.13-rc-smb3-part3' of git://git.samba.org/sfrench/cifs-2.6:
smb3: if max_channels set to more than one channel request multichannel
smb3: do not attempt multichannel to server which does not support it
smb3: when mounting with multichannel include it in requested capabilities
- Prevent PSI state corruption when schedule() races with cgroup move. A
recent commit combined two PSI callbacks to reduce the number of cgroup
tree updates, but missed that schedule() can drop rq::lock for load
balancing, which opens the race window for cgroup_move_task() which then
observes half updated state. The fix is to solely use task::ps_flags
instead of looking at the potentially mismatching scheduler state
- Prevent an out-of-bounds access in uclamp caused bu a rounding division
which can lead to an off-by-one error exceeding the buckets array size.
- Prevent unfairness caused by missing load decay when a task is attached
to a cfs runqueue. The old load of the task is attached to the runqueue
and never removed. Fix it by enforcing the load update through the
hierarchy for unthrottled run queue instances.
- A documentation fix fot the 'sched_verbose' command line option

- Two fixes for the futex syscall related to the timeout handling.
FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and because
it's not set the time namespace adjustment for clock MONOTONIC is
applied wrongly.
FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
always a relative timeout.
- Cleanups in the futex syscall entry points which became obvious when
the two timeout handling bugs were fixed.
- Cleanup of queued_write_lock_slowpath() as suggested by Linus
- Fixup of the smp_call_function_single_async() prototype
