ALSA: compress_offload: tighten ioctl command number checks
The snd_compr_ioctl() ignores the upper 24 bits of the ioctl command
number and only compares the number of the ioctl command, which can
cause unintended behavior if an application tries to use an unsupprted
command that happens to have the same _IOC_NR() value.
Remove the truncation to the low bits and compare the entire ioctl
command code like every other driver does.
When uloading snd_soc_avs module there is NULL pointer dereference.
It happens, because codec was moved into pdata and
avs_component_hda_unregister_dais() was not updated.

ALSA: hda/tas2781: Fix calibration data parser issue
We will copy calibration data from position behind to front.
We have created a variable (tmp_val) point on top of calibration data
buffer, and tmp_val[1] is max of node number in original calibration
data structure, it will be overwritten after first data copy,
so can't be used as max node number check in for loop.
So we create a new variable to save max of node number (tmp_val[1]),
used to check if max node number was reached in for loop.
And a point need to be increased to point at calibration data in node.
Data saved position also need to be increased one byte.

QEMU HD-audio device (1af4:0021) is handled by the generic HD-audio
codec driver, hence it's better to have an explicit device ID listing,
so that we can avoid the superfluous vendor driver matching.
The sanity check has been commented out for more than 12 years since
commit d5657ec9f4ad ("ALSA: hda - Disable the sanity check in
snd_hda_add_pincfg()") - remove it.
ASoC: cs35l56: probe() should fail if the device ID is not recognized
Return an error from driver probe if the DEVID read from the chip is not
one supported by this driver.
In cs35l56_hw_init() there is a check for valid DEVID, but the invalid
case was returning the value of ret. At this point in the code ret == 0
so the caller would think that cs35l56_hw_init() was successful.

ALSA: usb-audio: Improve filtering of sample rates on Focusrite devices
Previously we were filtering out only upper unsupported sampling rates.
This patch adds filtering of the lower unsupported sampling rates. As a
result there is 1:1 mapping between altsetting and supported rates.
The issue was found on a Scarlett 3rd Gen card (see linked bug), but the
same filtering is likely needed for the Scarlett 1st and 2nd Gen as well
as the older Clarett cards which lacks Valid Alternate Setting Control.

ASoC: fsl_sai: Force a software reset when starting in consumer mode
On an imx8mm platform with an external clock provider, when running the
receiver (arecord) and triggering an xrun with xrun_injection, we see a
channel swap/offset. This happens sometimes when running only the
receiver, but occurs reliably if a transmitter (aplay) is also
concurrently running.
It seems that the SAI loses track of frame sync during the trigger stop
-> trigger start cycle that occurs during an xrun. Doing just a FIFO
reset in this case does not suffice, and only a software reset seems to
get it back on track.
This looks like the same h/w bug that is already handled for the
producer case, so we now do the reset unconditionally on config disable.

Pull tracing fix from Steven Rostedt:
- Fix possible UAF on error path in filter_free_subsystem_filters()
When freeing a subsystem filter, the filter for the subsystem is
passed in to be freed and all the events within the subsystem will
have their filter freed too. In order to free without waiting for RCU
synchronization, list items are allocated to hold what is going to be
freed to free it via a call_rcu(). If the allocation of these items
fails, it will call the synchronization directly and free after that
(causing a bit of delay for the user).
The subsystem filter is first added to this list and then the filters
for all the events under the subsystem. The bug is if one of the
allocations of the list items for the event filters fail to allocate,
it jumps to the "free_now" label which will free the subsystem
filter, then all the items on the allocated list, and then the event
filters that were not added to the list yet. But because the
subsystem filter was added first, it gets freed twice.
The solution is to add the subsystem filter after the events, and
then if any of the allocations fail it will not try to free any of
them twice

were initially mapped but only the first was used and hence turned
into a UBUF rathan than an IOVEC iterator, and catching a case where
a retry would be done even if the previous segment wasn't full
- Small series fixing an issue making the vm unhappy if debugging is
turned on, hitting a VM_BUG_ON_PAGE()

which is a regression in this merge window

i2c: scx200_acb: depends on HAS_IOPORT
It already depends on X86_32, but that's also set for ARCH=um.
Recent changes made UML no longer have IO port access since
it's not needed, but this driver uses it. Build it only for
HAS_IOPORT. This is pretty much the same as depending on X86,
but on the off-chance that HAS_IOPORT will ever be optional
on x86 HAS_IOPORT is the real prerequisite.

Pull bcachefs fixes from Kent Overstreet:
- Lots of small check/repair fixes, primarily in subvol loop and
directory structure loop (when involving snapshots).
- Fix a few 6.16 regressions: rare UAF in the foreground allocator path
when taking a transaction restart from the transaction bump
allocator, and some small fallout from the change to log the error
being corrected in the journal when repairing errors, also some
fallout from the btree node read error logging improvements.
(Alan, Bharadwaj)
- New option: journal_rewind
This lets the entire filesystem be reset to an earlier point in time.
Note that this is only a disaster recovery tool, and right now there
are major caveats to using it (discards should be disabled, in
particular), but it successfully restored the filesystem of one of
the users who was bit by the subvolume deletion bug and didn't have
backups. I'll likely be making some changes to the discard path in
the future to make this a reliable recovery tool.
- Some new btree iterator tracepoints, for tracking down some
livelock-ish behaviour we've been seeing in the main data write path.

io_uring/kbuf: flag partial buffer mappings
A previous commit aborted mapping more for a non-incremental ring for
bundle peeking, but depending on where in the process this peeking
happened, it would not necessarily prevent a retry by the user. That can
create gaps in the received/read data.
Add struct buf_sel_arg->partial_map, which can pass this information
back. The networking side can then map that to internal state and use it
to gate retry as well.
Since this necessitates a new flag, change io_sr_msg->retry to a
retry_flags member, and store both the retry and partial map condition
in there.
