The SoC sound core will generate a driver name by normalizing the card
name. However, most of the time that name does not tell anything about
the driver and is therefore useless for this purpose.
Make the driver name more useful by setting it explicitly during card
initialization.

The Chuwi Hi8 tablet is using an analog mic on IN1 and has its
jack-detect connected to JD2_IN4N, instead of using the default
IN3 for its internal mic and JD1_IN4P for jack-detect.
It also only has 1 speaker.
Add a quirk applying the correct settings for this configuration.

simple-card checks DT links 2 times. 1st is for counting DAIs / links
to allocating memory, 2nd is for detecting DAIs.
To detecting DAIs as CPU-dummy -> dummy-Codec order when DPCM case,
it uses loops 2 times.
Because of this kind of complex background, it needs to use local
varuable for it, and each call-back functions need to care about it.
Now, 1st and 2nd DT link check are using same order,
thus we can share same code. This patch do it.

simple-card / audio-graph are assuming single CPU/Codec/Platform on
dai_link. Because of it, it is difficult to support Multi-CPU/Codec.

/sys/devices/virtual/sound/ctl-led/mic
+ card0
| + attach
| + detach
| ...
+ card1
+ attach
...
Operations:
attach and detach
- amixer style ID is accepted and easy strings for numid and
simple names
reset
- reset all associated kcontrol entries
list
- list associated kcontrol entries (numid values only)
Additional symlinks:
/sys/devices/virtual/sound/ctl-led/mic/card0/card ->
/sys/class/sound/card0
/sys/class/sound/card0/controlC0/led-mic ->

The recent laptops have usually two LEDs assigned to reflect
the speaker and microphone mute state. This implementation
adds a tiny layer on top of the control API which calculates
the state for those LEDs using the driver callbacks.
Two new access flags are introduced to describe the controls
which affects the audio path settings (an easy code change
for drivers).
The LED resource can be shared with multiple sound cards with
this code. The user space controls may be added to the state
chain on demand, too.
This code should replace the LED code in the HDA driver and
add a possibility to easy extend the other drivers (ASoC
codecs etc.).

This patch adds a function to find a match between pcm hw params and SSP
DAI config. Config is matched against sample rate and if match is found
current config is set. If match isn't found last matched config is left
as current i.e. current config is not touched. Functionality for SSP
DAIs with 1 config remains the same as before.

Currently SSP DAIs don't have hw params callback function as there
wasn't anything to setup after initial topology loading. After enabling
multiple DAI configs the current config can be sent in the callback.
This patch changes the way SSP config ipc is sent to the dsp. Before it
was only sent once in topology loading, but now it will be additionally
sent always when stream is opened. Mechanism is similar as with HDA
DAIs.

As tasks always wait and kill their io-wq on exec/exit, files are of no
more concern to us, so we don't need to specifically cancel them by hand
in those cases. Moreover we should not, because io_match_task() looks at
req->task->files now, which is always true and so leads to extra

This is racy - move the blocking into when the task is created and
we're marking it as PF_IO_WORKER anyway. The IO threads are now
prepared to handle signals like SIGSTOP as well, so clear that from

We go through various hoops to disallow signals for the IO threads, but
there's really no reason why we cannot just allow them. The IO threads
never return to userspace like a normal thread, and hence don't go through
normal signal processing. Instead, just check for a pending signal as part
of the work loop, and call get_signal() to handle it for us if anything
is pending.
With that, we can support receiving signals, including special ones like
SIGSTOP.

There were two problems (one of which could cause data corruption)
that were noticed with duplicate extents (ie reflink)
when debugging why various xfstests were being incorrectly skipped
(e.g. generic/138, generic/140, generic/142). First, we were not
updating the file size locally in the cache when extending a
file due to reflink (it would refresh after actimeo expires)
but xfstest was checking the size immediately which was still
0 so caused the test to be skipped. Second, we were setting
the target file size (which could shrink the file) in all cases
to the end of the reflinked range rather than only setting the
target file size when reflink would extend the file.

RHBZ: 1933527
Under SMB1 + POSIX, if an inode is reused on a server after we have read and
cached a part of a file, when we then open the new file with the
re-cycled inode there is a chance that we may serve the old data out of cache
to the application.
This only happens for SMB1 (deprecated) and when posix are used.
The simplest solution to avoid this race is to force a revalidate
on smb1-posix open.

My recent fixes to cifsacl to maintain inherited ACEs had
regressed modefromsid when an older ACL already exists.

Right now we're never calling get_signal() from PF_IO_WORKER threads, but
in preparation for doing so, don't handle a fatal signal for them. The
workers have state they need to cleanup when exiting, so just return
instead of calling do_exit() on their behalf. The threads themselves will
detect a fatal signal and do proper shutdown.

If there are not any dm devices, we need to zero the "dev" argument in
the first structure dm_name_list. However, this can cause out of
bounds write, because the "needed" variable is zero and len may be
less than eight.
Fix this bug by reporting DM_BUFFER_FULL_FLAG if the result buffer is
too small to hold the "nl->dev" value.

Dan's address bounces, and has been bouncing for some time as he moved
to other projects.
I believe TI should be more careful with this, and should assign
alternate contacts for their drivers.
Anyway what we can do now is to remove the obsolete address.

For AES256 encryption (GCM and CCM), we need to adjust the size of a few
fields to 32 bytes instead of 16 to accommodate the larger keys.
Also, the L value supplied to the key generator needs to be changed from
to 256 when these algorithms are used.
Keeping the ioctl struct for dumping keys of the same size for now.
Will send out a different patch for that one.

When executing the daemon test on Arm64 and x86 with Debian (Buster)
distro, both skip the test case with the log:
# ./perf test -v 76
76: daemon operations :
--- start ---
test child forked, pid 11687
test daemon list
trap: SIGINT: bad trap
./tests/shell/daemon.sh: 173: local: cpu-clock: bad variable name
test child finished with -2
---- end ----
daemon operations: Skip
So the error happens for the variable expansion when use local variable
in the shell script. Since Debian Buster uses dash but not bash as
non-interactive shell, when execute the daemon testing, it hits a known
issue for dash which was reported [1].
To resolve this issue, one option is to add double quotes for all local
variables assignment, so need to change the code from:
local line=`perf daemon --config ${config} -x: | head -2 | tail -1`
... to:
local line="`perf daemon --config ${config} -x: | head -2 | tail -1`"
But the testing script has bunch of local variables, this leads to big
changes for whole script.
On the other hand, the testing script asks to use the "local" feature
which is bash-specific, so this patch explicitly uses "#!/bin/bash" to
ensure running the script with bash.
After:
# ./perf test -v 76
76: daemon operations :
--- start ---
test child forked, pid 11329
test daemon list
test daemon reconfig
test daemon stop
test daemon signal
signal 12 sent to session 'test [11596]'
signal 12 sent to session 'test [11596]'
test daemon ping
test daemon lock
test child finished with 0
---- end ----
daemon operations: Ok
