Linus Torvalds e35d016590 sound fixes for 5.5-rc5
Nothing to worry at this stage but all nice small changes:
 - A regression fix for AMD GPU detection in HD-audio
 - A long-standing sleep-in-atomic fix for an ice1724 device
 - Usual suspects, the device-specific quirks for HD- and USB-audio

ASUS reported that there's an bass speaker in addition to internal
speaker and it uses DAC 0x02. It was not enabled in the commit
436e25505f ("ALSA: hda/realtek - Enable internal speaker of ASUS
UX431FLC") which only enables the amplifier and the front speaker.
This commit enables the bass speaker on top of the aforementioned
work to improve the acoustic experience.

Takashi Iwai 0aec96f589 ALSA: ice1724: Fix sleep-in-atomic in Infrasonic Quartet support code
Jia-Ju Bai reported a possible sleep-in-atomic scenario in the ice1724
driver with Infrasonic Quartet support code: namely, ice->set_rate
callback gets called inside ice->reg_lock spinlock, while the callback
in quartet.c holds ice->gpio_mutex.

This patch fixes the invalid call: it simply moves the calls of
ice->set_rate and ice->set_mclk callbacks outside the spinlock.

Takashi Iwai c366b3dbba ALSA: hda - Apply sync-write workaround to old Intel platforms, too
Klaus Ethgen reported occasional high CPU usages in his system that
seem caused by HD-audio driver.  The perf output revealed that it's
in the unsolicited event handling in the workqueue, and the problem
seems triggered by some communication stall between the controller and
the codec at the runtime or system resume.

Actually a similar phenomenon was seen in the past for other Intel
platforms, and we already applied the workaround to enforce sync-write
for CORB/RIRB verbs for Skylake and newer chipsets (commit
2756d9143a "ALSA: hda - Fix intermittent CORB/RIRB stall on Intel
chips").  Fortunately, the same workaround is applicable to the old
chipset, and the experiment showed the positive effect.

Based on the experiment result, this patch enables the sync-write
workaround for all Intel chipsets.  The only reason I hesitated to
apply this workaround was about the possibly slightly higher CPU usage.
But if the lack of sync causes a much severer problem even for quite
old chip, we should think this would be necessary for all Intel chips.

The format altsetting number may come from a quirk table and there does
not seem to be any other validation of it (the corresponding index is

Hui Wang 92adc96f8e ALSA: usb-audio: set the interface format after resume on Dell WD19
Recently we found the headset-mic on the Dell Dock WD19 doesn't work
anymore after s3 (s2i or deep), this problem could be workarounded by
closing (pcm_close) the app and then reopening (pcm_open) the app, so
this bug is not easy to be detected by users.

When problem happens, retire_capture_urb() could still be called
periodically, but the size of captured data is always 0, it could be
a firmware bug on the dock. Anyway I found after resuming, the
snd_usb_pcm_prepare() will be called, and if we forcibly run
set_format() to set the interface and its endpoint, the capture
size will be normal again. This problem and workaound also apply to
playback.

To fix it in the kernel, add a quirk to let set_format() run
forcibly once after resume.

We made the error message for the CORB/RIRB communication clearer by
upgrading to dev_WARN() so that user can notice better.  But this
struck us like a boomerang: now it caught syzbot and reported back as
a fatal issue although it's not really any too serious bug that worth
for stopping the whole system.

OK, OK, let's be softy, downgrade it to the standard dev_err() again.

Takashi Iwai 6fd739c04f ALSA: hda: Fix regression by strip mask fix
The commit e38e486d66 ("ALSA: hda: Modify stream stripe mask only
when needed") tried to address the regression by the unconditional
application of the stripe mask, but this caused yet another
regression for the previously working devices.  Namely, the patch
clears the azx_dev->stripe flag at snd_hdac_stream_clear(), but this
may be called multiple times before restarting the stream, so this
ended up with clearance of the flag for the whole time.

This patch fixes the regression by moving the azx_dev->stripe flag
clearance at the counter-part, the close callback of HDMI codec
driver instead.

The current PCM code doesn't initialize explicitly the buffers
allocated for PCM streams, hence it might leak some uninitialized
kernel data or previous stream contents by mmapping or reading the
buffer before actually starting the stream.

Since this is a common problem, this patch simply adds the clearance
of the buffer data at hw_params callback.  Although this does only
zero-clear no matter which format is used, which doesn't mean the
silence for some formats, but it should be OK because the intention is
just to clear the previous data on the buffer.

Hui Wang 5815bdfd7f ALSA: hda/realtek - Line-out jack doesn't work on a Dell AIO
After applying the fixup ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, the
Line-out jack works well. And instead of adding a new set of pin
definition in the pin_fixup_tbl, we put a more generic matching entry
in the fallback_pin_fixup_tbl.

Lukas Wunner 6e8aeda224 ALSA: hda/hdmi - Fix duplicate unref of pci_dev
Nicholas Johnson reports a null pointer deref as well as a refcount
underflow upon hot-removal of a Thunderbolt-attached AMD eGPU.
He's bisected the issue down to commit 586bc4aab8 ("ALSA: hda/hdmi -
fix vgaswitcheroo detection for AMD").

The commit iterates over PCI devices using pci_get_class() and
unreferences each device found, even though pci_get_class()
subsequently unreferences the device as well.  Fix it.

ASoC: Intel: common: work-around incorrect ACPI HID for CML boards
On CML boards with the RT5682 headset codec and RT1011 speaker
amplifier, the platform firmware exposes three ACPI HIDs
(10EC5682, 10EC1011 and MX98357A). The last HID is a mistake in
DSDT tables, which causes the wrong machine driver to be loaded.

This patch changes the key used to identify boards and changes the
order of entries in the table to load the correct machine driver.
The order does matter and should not be modified to work-around this
firmware issue.

ASoC: simple-card: Don't create separate link when platform is present
In normal sound case all DAIs are detected as CPU-Codec.
simple_dai_link_of supports the presence of a platform but it counts
it as a CPU DAI resulting in the creation of an extra link.

Adding a platform property to a link description like:

simple-audio-card,dai-link {
	cpu {
		sound-dai = <&sai1>;
	};
	plat {
		sound-dai = <&dsp>;
	};
	codec {
		sound-dai = <&wm8960>;
	}

will result in the creation of two links:
	* sai1 <-> wm8960
	* dsp  <-> wm8960

which is obviously not what we want. We just want one single link
with:
	* sai1 <-> wm8960 (and platform set to dsp).

ASoC: topology: Check return value for snd_soc_add_dai_link()
snd_soc_add_dai_link() might fail. This situation occurs for
instance in a very specific use case where a PCM device and a
Back End DAI link are given identical names in the topology.
When this happens, soc_new_pcm_runtime() fails and then
snd_soc_add_dai_link() returns -ENOMEM when called from
soc_tplg_fe_link_create(). Because of that, the link will not
get added into the card list, so any attempt to remove it later
ends up in a panic.

Fix that by checking the return status and free the memory in case
of an error.

Takashi Iwai 4cc8d6505a ALSA: pcm: oss: Avoid potential buffer overflows
syzkaller reported an invalid access in PCM OSS read, and this seems
to be an overflow of the internal buffer allocated for a plugin.
Since the rate plugin adjusts its transfer size dynamically, the
calculation for the chained plugin might be bigger than the given
buffer size in some extreme cases, which lead to such an buffer
overflow as caught by KASAN.

Fix it by limiting the max transfer size properly by checking against
the destination size in each plugin transfer callback.

Takashi Iwai 643a2cc99b ALSA: hda: hdmi - Keep old slot assignment behavior for Intel platforms
The commit 609f548534 ("ALSA: hda: hdmi - preserve non-MST PCM
routing for Intel platforms") tried to restore the old behavior wrt
assignment of the PCM slot for Intel platforms, but this didn't do it
right.  As found in the later discussion, a positive pipe id on Intel
platforms can be passed for single monitor attachment case.

This patch reverts the previous attempt and applies a simpler
workaround instead.  Actually, for Intel platforms, we can handle as
if per_pin->dev_id=0, assign the primary slot at the first try.  This
assures the compatible behavior with the previous versions regarding
the slot assignment.

Takashi Iwai e38e486d66 ALSA: hda: Modify stream stripe mask only when needed
The recent commit in HD-audio stream management for changing the
stripe control seems causing a regression on some platforms.  The
stripe control is currently used only by HDMI codec, and applying the
stripe mask unconditionally may lead to scratchy and static noises as
seen on some MacBooks.

For addressing the regression, this patch changes the stream
management code to apply the stripe mask conditionally only when the
codec driver requested.

Linus Torvalds 0da522107e compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to
 fs/compat_ioctl.c, which still has a couple of commands that need support
 for time64_t.
 
 In completely unrelated work, I spent time on cleaning up parts of this
 file in the past, moving things out into drivers instead.
 
 After Al Viro reviewed an earlier version of this series and did a lot
 more of that cleanup, I decided to try to completely eliminate the rest
 of it and move it all into drivers.
 
 This series incorporates some of Al's work and many patches of my own,
 but in the end stops short of actually removing the last part, which is
 the scsi ioctl handlers. I have patches for those as well, but they need
 more testing or possibly a rewrite.

Merge tag 'compat-ioctl-5.5' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground

Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
 "As part of the cleanup of some remaining y2038 issues, I came to
  fs/compat_ioctl.c, which still has a couple of commands that need
  support for time64_t.

  In completely unrelated work, I spent time on cleaning up parts of
  this file in the past, moving things out into drivers instead.

  After Al Viro reviewed an earlier version of this series and did a lot
  more of that cleanup, I decided to try to completely eliminate the
  rest of it and move it all into drivers.

  This series incorporates some of Al's work and many patches of my own,
  but in the end stops short of actually removing the last part, which
  is the scsi ioctl handlers. I have patches for those as well, but they
  need more testing or possibly a rewrite"

Jaroslav Kysela d2cd795c4e ALSA: hda - fixup for the bass speaker on Lenovo Carbon X1 7th gen
The auto-parser assigns the bass speaker to DAC3 (NID 0x06) which
is without the volume control. I do not see a reason to use DAC2,
because the shared output to all speakers produces the sufficient
and well balanced sound. The stereo support is enough for this
purpose (laptop).

Kai Vehmanen 609f548534 ALSA: hda: hdmi - preserve non-MST PCM routing for Intel platforms
Commit 5398e94fb7 ("ALSA: hda - Add DP-MST support for NVIDIA codecs")
introduced a slight change of behaviour how non-MST monitors are
assigned to PCMs on Intel platforms.

In the drm_audio_component.h interface, the third parameter
to pin_eld_notify() is pipe number. On Intel platforms, this value
is -1 for MST. On other platforms, a non-zero pipe id is used to
signal MST use.

This difference leads to some subtle differences in hdmi_find_pcm_slot()
with regards to how non-MST monitors are assigned to PCMs.
This patch restores the original behaviour on Intel platforms while
keeping the new allocation policy on other platforms.

Kai Vehmanen 0c0fe9e6b9 ALSA: hda: hdmi - fix kernel oops caused by invalid PCM idx
Add additional check in hdmi_find_pcm_slot() to not return
a pcm index that points to unallocated pcm. This could happen
if codec driver is set up in codec->mst_no_extra_pcms mode.
On some platforms, this leads to a kernel oops in snd_ctl_notify(),
called via update_eld().

Takashi Iwai 336820c437 ALSA: hda/realtek - Fix inverted bass GPIO pin on Acer 8951G
We've added the bass speaker support on Acer 8951G by the commit
00066e9733 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems
that the GPIO pin was wrongly set: while the commit turns off the bit
to power up the amp, the actual hardware reacts other way round,
i.e. GPIO bit on = amp on.

So this patch fixes the bug, turning on the GPIO bit 0x02 as default.
Since turning on the GPIO bit can be more easily managed with
alc_setup_gpio() call, we simplify the quirk code by integrating the
GPIO setup into the existing alc662_fixup_aspire_ethos_hp() and
dropping the whole ALC669_FIXUP_ACER_ASPIRE_ETHOS_SUBWOOFER quirk.

Kai Vehmanen ae254888f3 ALSA: hda: hdmi - fix regression in connect list handling
Fix regression in how intel_haswell_fixup_connect_list()
results are used in hda_read_pin_conn(). Use of
snd_hda_get_raw_connections() in hda_read_pin_conn() bypasses
the cache and thus also bypasses the overridden pin connection
list. On platforms that require the connection list fixup,
mux list will be empty and HDMI playback will fail to -EBUSY
at open.

Fix the regression in hda_read_pinn_conn(). Simplify code
as suggested by Takashi Iwai to remove old
intel_haswell_fixup_connect_list() and copy the cvt_nid list
directly and not use snd_hda_override_conn_list() at all.

ASoC: max98090: fix possible race conditions
max98090_interrupt() and max98090_pll_work() run in 2 different threads.
There are 2 possible races:

Note: M98090_REG_DEVICE_STATUS = 0x01.
Note: ULK == 0, PLL is locked; ULK == 1, PLL is unlocked.

max98090_interrupt      max98090_pll_work
----------------------------------------------
schedule max98090_pll_work
                        restart max98090 codec
receive ULK INT
                        assert ULK == 0
schedule max98090_pll_work (1).

In the case (1), the PLL is locked but max98090_interrupt unnecessarily
schedules another max98090_pll_work.

max98090_interrupt      max98090_pll_work      max98090 codec
----------------------------------------------------------------------
                                               ULK = 1
receive ULK INT
read 0x01
                                               ULK = 0 (clear on read)
schedule max98090_pll_work
                        restart max98090 codec
                                               ULK = 1
receive ULK INT
read 0x01
                                               ULK = 0 (clear on read)
                        read 0x01
                        assert ULK == 0 (2).

In the case (2), both max98090_interrupt and max98090_pll_work read
the same clear-on-read register.  max98090_pll_work would falsely
thought PLL is locked.
Note: the case (2) race is introduced by the previous commit ("ASoC:
max98090: exit workaround earlier if PLL is locked") to check the status
and exit the loop earlier in max98090_pll_work.

There are 2 possible solution options:
A. turn off ULK interrupt before scheduling max98090_pll_work; and turn
on again before exiting max98090_pll_work.
B. remove the second thread of execution.

Option A cannot fix the case (2) race because it still has 2 threads
access the same clear-on-read register simultaneously.  Although we
could suppose the register is volatile and read the status via I2C could
be much slower than the hardware raises the bits.

Option B introduces a maximum 10~12 msec penalty delay in the interrupt
handler.  However, it could only punish the jack detection by extra
10~12 msec.

Adopts option B which is the better solution overall.

ASoC: max98090: exit workaround earlier if PLL is locked
According to the datasheet, PLL lock time typically takes 2 msec and
at most takes 7 msec.

Check the lock status every 1 msec and exit the workaround if PLL is
locked.
