used for handling the output URBs.  It can be achieved gracefully with

The commit 51ab5d77dc ("ALSA: usb-audio: Properly match with audio

pair and bInterface fields to match with all those with a new macro
USB_AUDIO_CLASS().  However, it turned out that those are false
conversions; all those (but the unknown KeithMcMillen device) are
actually with vendor-specific interface class, hence the conversions
broke the matching.

This patch corrects those entries to the right one,
USB_DEVICE_VENDOR_SPEC() (and USB_DEVICE() for KeithMcMillen to be
sure), and drop the unused USB_AUDIO_CLASS macro again.

Takashi Iwai 51ab5d77dc ALSA: usb-audio: Properly match with audio interface class
There are a few entries in the quirk table that set the device ID with
USB_DEVICE() macro while having an extra bInterfaceClass field.  But
bInterfaceClass field is never checked unless the proper match_flags
is set, so those may match incorrectly with all interfaces.

Introduce another macro to match with the vid/pid pair and the audio
class interface, and apply it to such entries, so that they can match
properly.

Takashi Iwai 5436f59bc5 ALSA: usb-audio: Move device rename and profile quirks to an internal table
So far we've added the devices that need vendor/product string renames
or the profile setup into the standard quirk table in quirks-table.h.
This table is imported into the primary USB audio device entry, hence
it's all exported for the probing so that udev and co can take a look
at it.  OTOH, for renaming or profile setup, we don't need to expose
those explicit entries because the probe itself follows the standard
way.  That said, we're exposing unnecessarily too many entries.

This patch moves such internal quirk entries into the own table, and
reduces the exported device table size.  Along with the moving items,
re-arrange the entries in the proper order.

Hector Martin 1b7ecc241a ALSA: usb-audio: work around streaming quirk for MacroSilicon MS2109
Further investigation of the L-R swap problem on the MS2109 reveals that
the problem isn't that the channels are swapped, but rather that they
are swapped and also out of phase by one sample. In other words, the
issue is actually that the very first frame that comes from the hardware
is a half-frame containing only the right channel, and after that
everything becomes offset.

So introduce a new quirk field to drop the very first 2 bytes that come
in after the format is configured and a capture stream starts. This puts
the channels in phase and in the correct order.

Kai-Heng Feng f8c11eb7da ALSA: usb-audio: Add support for Lenovo ThinkStation P620
Lenovo ThinkStation P620 is like other TRX40 boards, is equipped with
two USB audio cards.

USB device (17aa:104d) provides functionality for Internal Speaker and
Front Headset. It's UAC v2, so it supports insertion control (jack
detection). However, when trying to get the connector status of the
speaker, an error occurs:
[    5.787405] usb 3-1: cannot get connectors status: req = 0x81, wValue = 0x200, wIndex = 0x1000, type = 0

Since the insertion control works perfectly for the headset, the error
for speaker is probably casued by connecting internally. So let's relax
the error for a bit if it's a speaker, and always reports it's connected.

USB device (17aa:1046) is for rear Line-in, Line-out and Microphone.
The insertion control works for all three jacks. However, there's an
Function Unit that doesn't work:
[    5.905415] usb 3-6: cannot get ctl value: req = 0x83, wValue = 0xc00, wIndex = 0x1300, type = 4
[    5.905418] usb 3-6: 19:0: cannot get min/max values for control 12 (id 19)

So turn off the FU to avoid the error.

Also, add specific card name for both devices, so userspace can easily
indentify both cards.

Takashi Iwai 9ab0cb309e ALSA: Replace the word "slave" in vmaster API
Follow the recent inclusive terminology guidelines and replace the
word "slave" in vmaster API.  I chose the word "follower" at this time
since it seems fitting for the purpose.

Note that the word "master" is kept in API, since it refers rather to
audio master volume control.

Also, while we're at it, a typo in comments is corrected, too.

Kees Cook 3f649ab728 treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

Takashi Iwai 9b7e5208a9 ALSA: usb-audio: Fix race against the error recovery URB submission
USB MIDI driver has an error recovery mechanism to resubmit the URB in
the delayed timer handler, and this may race with the standard start /
stop operations.  Although both start and stop operations themselves
don't race with each other due to the umidi->mutex protection, but
this isn't applied to the timer handler.

For fixing this potential race, the following changes are applied:

- Since the timer handler can't use the mutex, we apply the
  umidi->disc_lock protection at each input stream URB submission;
  this also needs to change the GFP flag to GFP_ATOMIC
- Add a check of the URB refcount and skip if already submitted
- Move the timer cancel call at disconnection to the beginning of the
  procedure; this assures the in-flight timer handler is gone properly
  before killing all pending URBs

indicate that the element is the usb_mixer_elem_info type or not, and

Takashi Iwai 862b2509d1 ALSA: usb-audio: Fix inconsistent card PM state after resume
When a USB-audio interface gets runtime-suspended via auto-pm feature,
the driver suspends all functionality and increment
chip->num_suspended_intf.  Later on, when the system gets suspended to
S3, the driver increments chip->num_suspended_intf again, skips the
device changes, and sets the card power state to
SNDRV_CTL_POWER_D3hot.  In return, when the system gets resumed from
S3, the resume callback decrements chip->num_suspended_intf.  Since
this refcount is still not zero (it's been runtime-suspended), the
whole resume is skipped.  But there is a small pitfall here.

The problem is that the driver doesn't restore the card power state
after this resume call, leaving it as SNDRV_CTL_POWER_D3hot.  So,
even after the system resume finishes, the card instance still appears
as if it were system-suspended, and this confuses many ioctl accesses
that are blocked unexpectedly.

In details, we have two issues behind the scene: one is that the card
power state is changed only when the refcount becomes zero, and
another is that the prior auto-suspend check is kept in a boolean
flag.  Although the latter problem is almost negligible since the
auto-pm feature is imposed only on the primary interface, but this can
be a potential problem on the devices with multiple interfaces.

This patch addresses those issues by the following:

- Replace chip->autosuspended boolean flag with chip->system_suspend
  counter

- At the first system-suspend, chip->num_suspended_intf is recorded to
  chip->system_suspend

- At system-resume, the card power state is restored when the
  chip->num_suspended_intf refcount reaches to chip->system_suspend,
  i.e. the state returns to the auto-suspended

Also, the patch fixes yet another hidden problem by the code
refactoring along with the fixes above: namely, when some resume
procedure failed, the driver left chip->num_suspended_intf that was
already decreased, and it might lead to the refcount unbalance.
In the new code, the refcount decrement is done after the whole resume
procedure, and the problem is avoided as well.

Takashi Iwai 7f5ad9c900 ALSA: usb-audio: Quirks for Gigabyte TRX40 Aorus Master onboard audio
Gigabyte TRX40 Aorus Master is equipped with two USB-audio devices,
a Realtek ALC1220-VB codec (USB ID 0414:a001) and an ESS SABRE9218 DAC
(USB ID 0414:a000).  The latter serves solely for the headphone output
on the front panel while the former serves for the rest I/Os (mostly
for the I/Os in the rear panel but also including the front mic).

Both chips do work more or less with the unmodified USB-audio driver,
but there are a few glitches.  The ALC1220-VB returns an error for an
inquiry to some jacks, as already seen on other TRX40-based mobos.
However this machine has a slightly incompatible configuration, hence
the existing mapping cannot be used as is.

Meanwhile the ESS chip seems working without any quirk.  But since
both audio devices don't provide any specific names, both cards appear
as "USB-Audio", and it's quite confusing for users.

This patch is an attempt to overcome those issues:

- The specific mapping table for ALC1220-VB is provided, reducing the
  non-working nodes and renaming the badly chosen controls.
  The connector map isn't needed here unlike other TRX40 quirks.

- For both USB IDs (0414:a000 and 0414:a001), provide specific card
  name strings, so that user-space can identify more easily; and more
  importantly, UCM profile can be applied to each.

Gustavo A. R. Silva 9ad06ebb9a ALSA: Replace zero-length array with flexible-array
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

Alexander Tsoy f0bd62b640 ALSA: usb-audio: Improve frames size computation
For computation of the the next frame size current value of fs/fps and
accumulated fractional parts of fs/fps are used, where values are stored
in Q16.16 format. This is quite natural for computing frame size for
asynchronous endpoints driven by explicit feedback, since in this case
fs/fps is a value provided by the feedback endpoint and it's already in
the Q format. If an error is accumulated over time, the device can
adjust fs/fps value to prevent buffer overruns/underruns.

But for synchronous endpoints the accuracy provided by these computations
is not enough. Due to accumulated error the driver periodically produces
frames with incorrect size (+/- 1 audio sample).

This patch fixes this issue by implementing a different algorithm for
frame size computation. It is based on accumulating of the remainders
from division fs/fps and it doesn't accumulate errors over time. This
new method is enabled for synchronous and adaptive playback endpoints.

Xiyu Yang 59e1947ca0 ALSA: usb-audio: Fix usb audio refcnt leak when getting spdif
snd_microii_spdif_default_get() invokes snd_usb_lock_shutdown(), which
increases the refcount of the snd_usb_audio object "chip".

When snd_microii_spdif_default_get() returns, local variable "chip"
becomes invalid, so the refcount should be decreased to keep refcount
balanced.

The reference counting issue happens in several exception handling paths
of snd_microii_spdif_default_get(). When those error scenarios occur
such as usb_ifnum_to_if() returns NULL, the function forgets to decrease
the refcnt increased by snd_usb_lock_shutdown(), causing a refcnt leak.

Fix this issue by jumping to "end" label when those error scenarios
occur.

Takashi Iwai fef66ae73a ALSA: usb-audio: Add connector notifier delegation
It turned out that ALC1220-VB USB-audio device gives the interrupt
event to some PCM terminals while those don't allow the connector
state request but only the actual I/O terminals return the request.
The recent commit 7dc3c5a017 ("ALSA: usb-audio: Don't create jack
controls for PCM terminals") excluded those phantom terminals, so
those events are ignored, too.

My first thought was that this could be easily deduced from the
associated terminals, but some of them have even no associate terminal
ID, hence it's not too trivial to figure out.

Since the number of such terminals are small and limited, this patch
implements another quirk table for the simple mapping of the
connectors.  It's not really scalable, but let's hope that there will
be not many such funky devices in future.

The Miditech MIDIFACE 16x16 (USB ID 1290:1749) has more than one extra
endpoint descriptor.

The first extra descriptor is: 0x06 0x30 0x00 0x00 0x00 0x00

As the code in snd_usbmidi_get_ms_info() looks only at the
first extra descriptor to find USB_DT_CS_ENDPOINT the device
as such is recognized but there is neither input nor output
configured.

The patch iterates through the extra descriptors to find the
proper one. With this patch the device is correctly configured.

Takashi Iwai a4aad5636c ALSA: usb-audio: Inform devices that need delayed registration
The USB-audio driver may call snd_card_register() multiple times as
its probe function is per USB interface while some USB-audio devices
may provide multiple interfaces to assign different streams although
they belong to the same device.  This works in most cases but the
registration is racy, hence it may miss the device recognition,
e.g. PA doesn't see certain devices when hotplugged.

The recent addition of the delayed registration quirk allows to sync
the registration at the last known interface, and the previous commit
added a new module option to allow the dynamic setup for that
purpose.

Now, this patch tries to find out and notifies for such devices that
require the delayed registration.  It shows a message like:

  Found post-registration device assignment: 1234abcd:02

If you hit this message, you can pass delayed_register module option
like:

  snd_usb_audio.delayed_register=1234abcd:02

by just copying the last shown entry.  If this works, it can be added
statically in the quirk list, registration_quirks[] found at the end
of sound/usb/quirks.c.

Takashi Iwai d683469b3c ALSA: line6: Fix endless MIDI read loop
The MIDI input event parser of the LINE6 driver may enter into an
endless loop when the unexpected data sequence is given, as it tries
to continue the secondary bytes without termination.  Also, when the
input data is too short, the parser returns a negative error, while
the caller doesn't handle it properly.  This would lead to the
unexpected behavior as well.

This patch addresses those issues by checking the return value
correctly and handling the one-byte event in the parser properly.

The bug was reported by syzkaller.

- MaxPacketsOnly attribute is erroneously set in endpoint descriptors.

- Sample rate changes takes more than 2 seconds for this device. Clock

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertenly introduced[3] to the codebase from now on.

This issue was found with the help of Coccinelle.

Arvind Sankar 93f9d1a4ac ALSA: usb-audio: Apply sample rate quirk for Audioengine D1
The Audioengine D1 (0x2912:0x30c8) does support reading the sample rate,
but it returns the rate in byte-reversed order.

When setting sampling rate, the driver produces these warning messages:
[168840.944226] usb 3-2.2: current rate 4500480 is different from the runtime rate 44100
[168854.930414] usb 3-2.2: current rate 8436480 is different from the runtime rate 48000
[168905.185825] usb 3-2.1.2: current rate 30465 is different from the runtime rate 96000

As can be seen from the hexadecimal conversion, the current rate read
back is byte-reversed from the rate that was set.

44100 == 0x00ac44, 4500480 == 0x44ac00
48000 == 0x00bb80, 8436480 == 0x80bb00
96000 == 0x017700,   30465 == 0x007701

Rather than implementing a new quirk to reverse the order, just skip
checking the rate to avoid spamming the log.

Takashi Iwai d75a170fd8 ALSA: usb-audio: Fix UAC2/3 effect unit parsing
We've got a regression report about M-Audio Fast Track C400 device,
and the git bisection resulted in the commit e0ccdef926 ("ALSA:
usb-audio: Clean up check_input_term()").  This commit was about the
rewrite of the input terminal parser, and it's not too obvious from
the change what really broke.  The answer is: it's the interpretation
of UAC2/3 effect units.

In the original code, UAC2 effect unit is as if through UAC1
processing unit because both UAC1 PU and UAC2/3 EU share the same
number (0x07).  The old code went through a complex switch-case
fallthrough, finally bailing out in the middle:

  if (protocol == UAC_VERSION_2 &&
      hdr[2] == UAC2_EFFECT_UNIT) {
         /* UAC2/UAC1 unit IDs overlap here in an
          * uncompatible way. Ignore this unit for now.
          */
         return 0;
   }

... and this special handling was missing in the new code; the new
code treats UAC2/3 effect unit as if it were equivalent with the
processing unit.

Actually, the old code was too confusing.  The effect unit has an
incompatible unit description with the processing unit, so we
shouldn't have dealt with EU in the same way.

This patch addresses the regression by changing the effect unit
handling to the own parser function.  The own parser function makes
the clear distinct with PU, so it improves the readability, too.

The EU parser just sets the type and the id like the old kernels.
Once when the proper effect unit support is added, we can revisit this
parser function, but for now, let's keep this simple setup as is.

Takashi Iwai 5b29f05396 ALSA: usb-audio: Use pcm_for_each_format() macro for PCM format iterations
The new macro can fix the sparse warnings gracefully:
  sound/usb/proc.c:73:31: warning: restricted snd_pcm_format_t degrades to integer
  sound/usb/proc.c:73:38: warning: restricted snd_pcm_format_t degrades to integer
  sound/usb/proc.c:73:61: warning: restricted snd_pcm_format_t degrades to integer

No functional changes, just sparse warning fixes.

Takashi Iwai d8f489355c ALSA: usb-audio: Annotate endianess in Scarlett gen2 quirk
The Scarlett gen2 mixer quirk code defines a few record types to
communicate via USB hub, and those must be all little-endian.
This patch changes the field types to LE to annotate endianess
properly.  It also fixes the incorrect usage of leXX_to_cpu() in a
couple of places, which was caught by sparse after this change.

Takashi Iwai f8e5f90b3a ALSA: usb-audio: Fix endianess in descriptor validation
I overlooked that some fields are words and need the converts from
LE in the recently added USB descriptor validation code.
This patch fixes those with the proper macro usages.

devices but the quirks is still needed.

Add it to the quirk list for line6 helix family of devices.

Thanks to Jens for pointing out the missing ids.

Alexander Tsoy c249177944 ALSA: usb-audio: add implicit fb quirk for MOTU M Series
This fixes crackling sound during playback.

Further note: MOTU is known for reusing Product IDs for different
devices or different generations of the device (e.g. MicroBook
I/II/IIc shares a single Product ID). This patch was only tested with
M4 audio interface, but the same Product ID is also used by M2. Hope
it will work for M2 as well.

Johan Hovold 5d1b71226d ALSA: usb-audio: fix sync-ep altsetting sanity check
The altsetting sanity check in set_sync_ep_implicit_fb_quirk() was
checking for there to be at least one altsetting but then went on to
access the second one, which may not exist.

This could lead to random slab data being used to initialise the sync
endpoint in snd_usb_add_endpoint().
