When using callback there was a flow of
ret = -EINVAL
if (callback) {
offset = callback();
goto out;
}
...
offset = some other value in case of no callback;
ret = offset;
out:
return ret;
which causes the snd_info_entry_llseek() to return -EINVAL when there is
callback handler. Fix this by setting "ret" directly to callback return
value before jumping to "out".

ASoC: Fixes for v6.0
A relatively large batch of fixes that came in since my pull request,
none of them too major and mostly device specific apart from a series of
security/robustness improvements from Takashi.
With jackpoll_in_suspend flag set, there is a possibility that
jack poll worker thread will run even after system suspend was
completed. Any register access after system pm callback flow
will result in kernel crash as still jack poll worker thread
tries to access registers.
To fix the crash issue during system flow, cancel the jack poll
worker thread during system pm prepare callback and cancel the
worker thread at start of runtime suspend callback and re-schedule
at last to avoid any unwarranted access of register by worker thread
during suspend flow.

The first two fixes should be straightforward.
The latter two clean up what looks to me like a mess in the setting of
power levels. However we settle it, we should then do the same changes
to TAS2764, which has the same template (and maybe there are other
drivers).
ASUS ROG Zenith II has two USB interfaces, one for the front headphone
and another for the rest I/O. Currently we provided the mixer mapping
for the latter but with an incomplete form.
This patch corrects and provides more comprehensive mixer mapping, as
well as providing the proper device names for both the front headphone
and main audio.

The Focusrite Clarett+ 8Pre uses the same protocol as the Scarlett Gen
2 and Gen 3 product range. This patch adds support for the Clarett+
8Pre by adding appropriate entries to the scarlett2 driver.
The Clarett+ 2Pre and 4Pre, and the Clarett USB product line
presumably use the same protocol as well, so support for them can
easily be added if someone can test.

Because the PWR_CTRL field is modeled as the power state of the DAC
widget, and at the same time it is used to implement mute/unmute, we
need some additional book-keeping to have the right end result no matter
the sequence of calls. Without this fix, one can mute an ongoing stream
by toggling a speaker pin control.

The driver is setting the PWR_CTRL field in both the set_bias_level
callback and on DAPM events of the DAC widget (and also in the
mute_stream method). Drop the set_bias_level callback altogether as the
power setting it does is in conflict with the other code paths.

Merge series from Takashi Iwai <tiwai@suse.de>:
This is a patch series to paper over the theoretical buffer overflow
that might be caused by snprintf(). snprintf() is notorious for its
behavior and the usage of a safer version, scnprintf(), is
recommended.
When DPCM tries to add valid BE connections at dpcm_add_paths(), it
doesn't check whether the picked BE actually supports for the given
stream direction. Due to that, when an asymmetric BE stream is
present, it picks up wrongly and this may result in a NULL dereference
at a later point where the code assumes the existence of a
corresponding BE substream.
This patch adds the check for the presence of the substream for the
target BE for avoiding the problem above.
Note that we have already some fix for non-existing BE substream at
commit 6246f283d5 ("ASoC: dpcm: skip missing substream while
applying symmetry"). But the code path we've hit recently is rather
happening before the previous fix. So this patch tries to fix at
picking up a BE instead of parsing BE lists.

ASoC: More updates for v5.20
More updates that came in since the last pull request I sent, a series
of driver specific changes:
- Support for AMD RPL, some Intel platforms and Mediatek MT8186.
The Lenovo Yoga 9 14IAP7 is set up similarly to the Thinkpad X1 7th and
8th Gen. It also has the speakers attached to NID 0x14 and the bass
speakers to NID 0x17, but here the codec misreports the NID 0x17 as
unconnected.
The pincfg and hda verbs connect and activate the bass speaker
amplifiers, but the generic driver will connect them to NID 0x06 which
has no volume control. Set connection list/preferred connections is
required to gain volume control.

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.
