[ Upstream commit 901e85677ec0bb9a69fb9eab1feafe0c4eb7d07e ]

For an invalid input value that is out of the given range, currently
USB-audio driver corrects the value silently and accepts without
errors.  This is no wrong behavior, per se, but the recent kselftest
rather wants to have an error in such a case, hence a different
behavior is expected now.

This patch adds a sanity check at each control put for the standard
mixer types and returns an error if an invalid value is given.

Note that this covers only the standard mixer types.  The mixer quirks
that have own control callbacks would need different coverage.

[ Upstream commit 6aa8700150f7dc62f60b4cf5b1624e2e3d9ed78e ]

Registering Numark Party Mix II fails with error 'bogus bTerminalLink 1'.
The problem stems from the driver not being able to find input/output
terminals required to configure audio streaming. The information about
those terminals is stored in AudioControl Interface. Numark device
contains 2 AudioControl Interfaces and the driver checks only one of them.

According to the USB standard, a device can have multiple audio functions,
each represented by Audio Interface Collection. Every audio function is
considered to be closed box and will contain unique AudioControl Interface
and zero or more AudioStreaming and MIDIStreaming Interfaces.

The Numark device adheres to the standard and defines two audio functions:
- MIDIStreaming function
- AudioStreaming function
It starts with MIDI function, followed by the audio function. The driver
saves the first AudioControl Interface in `snd_usb_audio` structure
associated with the entire device. It then attempts to use this interface
to query for terminals and clocks. However, this fails because the correct
information is stored in the second AudioControl Interface, defined in the
second Audio Interface Collection.

This patch introduces a structure holding association between each
MIDI/Audio Interface and its corresponding AudioControl Interface,
instead of relying on AudioControl Interface defined for the entire
device. This structure is populated during usb probing phase and leveraged
later when querying for terminals and when sending USB requests.

Alternative solutions considered include:
- defining a quirk for Numark where the order of interface is manually
changed, or terminals are hardcoded in the driver. This solution would
have fixed only this model, though it seems that device is USB compliant,
and it also seems that other devices from this company may be affected.
What's more, it looks like products from other manufacturers have similar
problems, i.e. Rane One DJ console
- keeping a list of all AudioControl Interfaces and querying all of them
to find required information. That would have solved my problem and have
low probability of breaking other devices, as we would always start with
the same logic of querying first AudioControl Interface. This solution
would not have followed the standard though.

This patch preserves the `snd_usb_audio.ctrl_intf` variable, which holds
the first AudioControl Interface, and uses it as a fallback when some
interfaces are not parsed correctly and lack an associated AudioControl
Interface, i.e., when configured via quirks.

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 0c3ad39b791c2ecf718afcaca30e5ceafa939d5c ]

Many entries in the USB-audio quirk tables have relatively complex
expressions.  For improving the readability, introduce a few macros.
Those are applied in the following patch.

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit d79e13f8e8abb5cd3a2a0f9fc9bc3fc750c5b06f ]

Apply the newly introduced macros for reduce the complex expressions
and cast in the quirk table definitions.  It results in a significant
code reduction, too.

There should be no functional changes.

[ Upstream commit c032044e9672408c534d64a6df2b1ba14449e948 ]

Add trivial support for audio streaming on the RME Digiface USB. Binds
only to the first interface to allow userspace to directly drive the
complex I/O and matrix mixer controls.

[ Upstream commit 611a96f6acf2e74fe28cb90908a9c183862348ce ]

Implement sync, output format, and input status mixer controls, to allow
the interface to be used as a straight ADAT/SPDIF (+ Headphones) I/O
interface.

This does not implement the matrix mixer, output gain controls, or input
level meter feedback. The full mixer interface is only really usable
using a dedicated userspace control app (there are too many mixer nodes
for alsamixer to be usable), so for now we leave it up to userspace to
directly control these features using raw USB control messages. This is
similar to how it's done with some FireWire interfaces (ffado-mixer).

[ Upstream commit 2fbf16992e5aa14acf0441320033a01a32309ded ]

If reading version and variant from registers fails (which is unlikely
but possible, because it is a read over bus), the driver will proceed
and perform device configuration based on uninitialized stack variables.
Handle it a bit better - bail out without doing any init and failing the
update status Soundwire callback.

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit fcc62b19104a67b9a2941513771e09389b75bd95 ]

The code path for kcontrol accesses have often nested locks of both
card's controls_rwsem and power_ref, and applies in that order.
However, what could take much longer is the latter, power_ref; it
waits for the power state of the device, and it pretty much depends on
the user's action.

This patch swaps the locking order of those locks to a more natural
way, namely, power_ref -> controls_rwsem, in order to shorten the time
of possible nested locks.  For consistency, power_ref is taken always
in the top-level caller side (that is, *_user() functions and the
ioctl handler itself).

ASIHPI driver stores some values in the static array upon a response
from the driver, and its index depends on the firmware.  We shouldn't
trust it blindly.

This patch adds a sanity check of the array index to fit in the array
size.

[ Upstream commit c01f3815453e2d5f699ccd8c8c1f93a5b8669e59 ]

The current MIDI input flush on HDSP and HDSPM drivers relies on the
hardware reporting the right value.  If the hardware doesn't give the
proper value but returns -1, it may be stuck at an infinite loop.

Add a counter and break if the loop is unexpectedly too long.

[ Upstream commit fd69dfe6789f4ed46d1fdb52e223cff83946d997 ]

I have been wondering why DPCM needs special flag (= dpcm_playback/capture)
to use it. Below is the history why it was added to ASoC.

(A) In beginning, there was no dpcm_xxx flag on ASoC.
    It checks channels_min for DPCM, same as current non-DPCM.
    Let's name it as "validation check" here.

	if (rtd->dai_link->dynamic || rtd->dai_link->no_pcm) {
		if (cpu_dai->driver->playback.channels_min)
			playback = 1;
		if (cpu_dai->driver->capture.channels_min)
			capture = 1;

(B) commit 1e9de42f4324 ("ASoC: dpcm: Explicitly set BE DAI link supported
    stream directions") force to use dpcm_xxx flag on DPCM. According to
    this commit log, this is because "Some BE dummy DAI doesn't set
    channels_min for playback/capture". But we don't know which DAI is it,
    and not know why it can't/don't have channels_min. Let's name it as
    "no_chan_DAI" here. According to the code and git-log, it is used as
    DCPM-BE and is CPU DAI. I think the correct solution was set
    channels_min on "no_chan_DAI" side, not update ASoC framework side. But
    everything is under smoke today.

	if (rtd->dai_link->dynamic || rtd->dai_link->no_pcm) {
		playback = rtd->dai_link->dpcm_playback;
		capture  = rtd->dai_link->dpcm_capture;

(C) commit 9b5db059366a ("ASoC: soc-pcm: dpcm: Only allow playback/capture
    if supported") checks channels_min (= validation check) again. Because
    DPCM availability was handled by dpcm_xxx flag at that time, but some
    Sound Card set it even though it wasn't available. Clearly there's
    a contradiction here. I think correct solution was update Sound Card
    side instead of ASoC framework. Sound Card side will be updated to
    handle this issue later (commit 25612477d20b ("ASoC: soc-dai: set
    dai_link dpcm_ flags with a helper"))

	if (rtd->dai_link->dynamic || rtd->dai_link->no_pcm) {
		...
		playback = rtd->dai_link->dpcm_playback &&
			   snd_soc_dai_stream_valid(cpu_dai, ...);
		capture = rtd->dai_link->dpcm_capture &&
			   snd_soc_dai_stream_valid(cpu_dai, ...);

This (C) patch should have broken "no_chan_DAI" which doesn't have
channels_min, but there was no such report during this 4 years.
Possibilities case are as follows
	- No one is using "no_chan_DAI"
	- "no_chan_DAI" is no longer exist : was removed ?
	- "no_chan_DAI" is no longer exist : has channels_min ?

Because of these history, this dpcm_xxx is unneeded flag today. But because
we have been used it for 10 years since (B), it may have been used
differently. For example some DAI available both playback/capture, but it
set dpcm_playback flag only, in this case dpcm_xxx flag is used as
availability limitation. We can use playback_only flag instead in this
case, but it is very difficult to find such DAI today.

Let's add grace time to remove dpcm_playback/capture flag.

This patch don't use dpcm_xxx flag anymore, and indicates warning to use
xxx_only flag if both playback/capture were available but using only
one of dpcm_xxx flag, and not using xxx_only flag.

[ Upstream commit 14e91ddd5c02d8c3e5a682ebfa0546352b459911 ]

The code seems mostly copy-pasted, with some machine drivers
forgetting to test if the 'adev' result is NULL.

Add this check when missing, and use -ENOENT consistently as an error
code.
