commit ffdd98277f0a1d15a67a74ae09bee713df4c0dbc upstream.
Like the previous fix (commit c0317c0e8709 "ALSA: timer: Fix
use-after-free problem"), we have to unlink slave timer instances
immediately at snd_timer_stop(), too. Otherwise it may leave a stale
entry in the list if the slave instance is freed before actually
running.

commit c0317c0e87094f5b5782b6fdef5ae0a4b150496c upstream.
When the timer instance was add into ack_list but was not currently in
process, the user could stop it via snd_timer_stop1() without delete it
from the ack_list. Then the user could free the timer instance and when
it was actually processed UAF occurred.
This issue could be reproduced via testcase snd_timer01 in ltp - running
several instances of that testcase at the same time.
What I actually met was that the ack_list of the timer broken and the
kernel went into deadloop with irqoff. That could be detected by
hardlockup detector on board or when we run it on qemu, we could use gdb
to dump the ack_list when the console has no response.
To fix this issue, we delete the timer instance from ack_list and
active_list unconditionally in snd_timer_stop1().

commit 8e537d5dec34cac746dd6abf6a83e5de3aa471fc upstream.
The recent refactoring of mmap handling caused Oops on some devices

commit 43d35ccc36dad52377dd349b2e3ea803b72c3906 upstream.
The recent fix for setting up the DMA buffer type on RME drivers tried
to address the non-standard memory managements and changed the DMA
buffer information to the standard snd_dma_buffer object that is
allocated at the probe time. However, I overlooked that the RME
drivers handle the buffer addresses based on 64k alignment, and the
previous conversion broke that silently.
This patch is an attempt to fix the regression. The snd_dma_buffer
objects are copied to the original data with the correction to the
aligned accesses, and those are passed to snd_pcm_set_runtime_buffer()
helpers instead. The original snd_dma_buffer objects are managed by
devres, hence they'll be released automagically.

commit 39173303c83859723dab32c2abfb97296d6af3bf upstream.
The recent change in hda-intel driver to allow repeated probes
surfaced a problem that has been hidden until; the probe process in
the work calls azx_free() at the error path, and this skips the card
free process that eventually releases codec instances. As a result,
we get a kernel WARNING like:
snd_hda_intel 0000:00:1f.3: Cannot probe codecs, giving up
------------[ cut here ]------------
WARNING: CPU: 14 PID: 186 at sound/hda/hdac_bus.c:73
....
For fixing this, we need to call snd_card_free() instead of
azx_free(). Additionally, the device drvdata has to be cleared, as
the driver binding itself is still active. Then the PM and other
driver callbacks will ignore the procedure.

When a Jieli Technology USB Webcam is connected, the video part works
well, but the mic sound is speeded up. On dmesg there are messages
about different rates from the runtime rates, warnings about volume
resolution and lastly, the log is filled, every 5 seconds, with
retire_capture_urb error messages.
The mic works only when ep packet size is set to wMaxPacketSize (normal
sound and no more retire_capture_urb error messages). Skipping reading
sample rate, fixes the messages about different rates and forcing a volume
resolution, fixes warnings about volume range. I have arbitrarily choosed
the value (16): I read in a comment that there should be no more than 255
levels, so 4096 (max volume) / 16 = 0-255.

In laptop 'HP Spectre x360 Convertible 15-eb1xxx/8811' both front and
rear speakers are silent, this patch fixes that by overriding the pin
layout and by initializing the amplifier which needs a GPIO pin to be
set to 1 then 0, similar to the existing HP Spectre x360 14 model.
In order to have volume control, both front and rear speakers were
forced to use the DAC1.
This patch also correctly map the mute LED but since there is no
microphone on/off switch exposed by the alsa subsystem it never turns
on by itself.
There are still known audio issues in this laptop: headset microphone
doesn't work, the button to mute/unmute microphone is not yet mapped,
the LED of the mute/unmute speakers doesn't seems to be exposed via
GPIO and never turns on.

There is a noise issue for 8kHz sample rate on slave mode.
Compared with master mode, the difference is the DACDIV
setting, after correcting the DACDIV, the noise is gone.
There is no noise issue for 48kHz sample rate, because
the default value of DACDIV is correct for 48kHz.
So wm8960_configure_clocking() should be functional for
ADC and DAC function even if it is slave mode.
In order to be compatible for old use case, just add

The snd_hdac_bus_reset_link() contains logic to clear STATESTS register
before performing controller reset. This code dates back to an old
bugfix in commit e8a7f136f5ed ("[ALSA] hda-intel - Improve HD-audio
codec probing robustness"). Originally the code was added to
azx_reset().
The code was moved around in commit a41d122449be ("ALSA: hda - Embed bus
into controller object") and ended up to snd_hdac_bus_reset_link() and
called primarily via snd_hdac_bus_init_chip().
The logic to clear STATESTS is correct when snd_hdac_bus_init_chip() is
called when controller is not in reset. In this case, STATESTS can be
cleared. This can be useful e.g. when forcing a controller reset to retry
codec probe. A normal non-power-on reset will not clear the bits.
However, this old logic is problematic when controller is already in
reset. The HDA specification states that controller must be taken out of
reset before writing to registers other than GCTL.CRST (1.0a spec,
3.3.7). The write to STATESTS in snd_hdac_bus_reset_link() will be lost
if the controller is already in reset per the HDA specification mentioned.
This has been harmless on older hardware. On newer generation of Intel
PCIe based HDA controllers, if configured to report issues, this write
will emit an unsupported request error. If ACPI Platform Error Interface
(APEI) is enabled in kernel, this will end up to kernel log.
Fix the code in snd_hdac_bus_reset_link() to only clear the STATESTS if
the function is called when controller is not in reset. Otherwise
clearing the bits is not possible and should be skipped.

sound at all. Because most of the headset are ctia type nowadays and
some machines have the fixed ctia type audio jack, it is possible this
machine has the fixed ctia jack too. Here we set this mic jack to
fixed ctia type, this could avoid the mic type detection mistake and
make the ctia headset work stable.

Michael Forney reported an incorrect padding type that was defined in
the commit 80fe7430c708 ("ALSA: add new 32-bit layout for
snd_pcm_mmap_status/control") for PCM control mmap data.
His analysis is correct, and this caused the misplacements of PCM
control data on 32bit arch and 32bit compat mode.
The bug is that the __pad2 definition in __snd_pcm_mmap_control64
struct was wrongly with __pad_before_uframe, which should have been
__pad_after_uframe instead. This struct is used in SYNC_PTR ioctl and
control mmap. Basically this bug leads to two problems:
- The offset of avail_min field becomes wrong, it's placed right after
appl_ptr without padding on little-endian
- When appl_ptr and avail_min are read as 64bit values in kernel side,
the values become either zero or corrupted (mixed up)
One good news is that, because both user-space and kernel
misunderstand the wrong offset, at least, 32bit application running on
32bit kernel works as is. Also, 64bit applications are unaffected
because the padding size is zero. The remaining problem is the 32bit
compat mode; as mentioned in the above, avail_min is placed right
after appl_ptr on little-endian archs, 64bit kernel reads bogus values
for appl_ptr updates, which may lead to streaming bugs like jumping,
XRUN or whatever unexpected.
(However, we haven't heard any serious bug reports due to this over
years, so practically seen, it's fairly safe to assume that the impact
by this bug is limited.)
Ideally speaking, we should correct the wrong mmap status control
definition. But this would cause again incompatibility with the
existing binaries, and fixing it (e.g. by renumbering ioctls) would be
really messy.
So, as of this patch, we only correct the behavior of 32bit compat
mode and keep the rest as is. Namely, the SYNC_PTR ioctl is now
handled differently in compat mode to read/write the 32bit values at
the right offsets. The control mmap of 32bit apps on 64bit kernels
has been already disabled (which is likely rather an overlook, but
this worked fine at this time :), so covering SYNC_PTR ioctl should
suffice as a fallback.

The put callback of a kcontrol is supposed to return 1 when the value
is changed, and this will be notified to user-space. However, some
DAPM kcontrols always return 0 (except for errors), hence the
user-space misses the update of a control value.
This patch corrects the behavior by properly returning 1 when the
value gets updated.

It seems that a few recent AMD systems show the codec configuration
errors at the early boot, while loading the driver at a later stage
works magically. Although the root cause of the error isn't clear,
it's certainly not bad to allow retrying the codec probe in such a
case if that helps.
This patch adds the capability for retrying the probe upon codec probe
errors on the certain AMD platforms. The probe_work is changed to a
delayed work, and at the secondary call, it'll jump to the codec
probing.
Note that, not only adding the re-probing, this includes the behavior
changes in the codec configuration function. Namely,
snd_hda_codec_configure() won't unregister the codec at errors any
longer. Instead, its caller, azx_codec_configure() unregisters the
codecs with the probe failures *if* any codec has been successfully
configured. If all codec probe failed, it doesn't unregister but let
it re-probed -- which is the most case we're seeing and this patch
tries to improve.
Even if the driver doesn't re-probe or give up, it will go to the
"free-all" error path, hence the leftover codecs shall be disabled /
deleted in anyway.

This applies a SND_PCI_QUIRK(...) to the TongFang PHxTxX1 barebone. This
fixes the issue of the internal Microphone not working after booting
another OS.
When booting a certain another OS this barebone keeps some coeff settings
even after a cold shutdown. These coeffs prevent the microphone detection
from working in Linux, making the Laptop think that there is always an
external microphone plugged-in and therefore preventing the use of the
internal one.
The relevant indexes and values where gathered by naively diff-ing and
reading a working and a non-working coeff dump.

The Scarlett device series from Focusrite Novation seem requiring the
sample rate validations as we've done for MOTU devices; otherwise the
driver probes invalid audioformat entries that contain the sample
rates that actually don't work, and this may result in an incomplete
setup as reported recently.
This patch adds the needed quirk flag for enabling the sample rate
validation for Focusrite Novation devices.

The headphone mic is not working on Dell Latitude laptops with ALC3254.
The codec vendor id is 0x10ec0295 and share the same pincfg as defined
in ALC295_STANDARD_PINS. So the ALC269_FIXUP_DELL1_MIC_NO_PRESENCE will
be applied per alc269_pin_fixup_tbl[] but actually the headphone mic is
using NID 0x1b instead of 0x1a. The ALC269_FIXUP_DELL4_MIC_NO_PRESENCE
need to be applied instead.
Use ALC269_FIXUP_DELL4_MIC_NO_PRESENCE for particular models before
a generic fixup comes out.
