There are a couple of device-specific quirks in the clock setup code,
and those can be moved gracefully to quirk_flags, too.

The snd_usb_audio.playback_first flag is used by the implicit feedback
mode handling, and this can be also moved to quirk_flags.

There is another quirk for the transfer, and that's currently specific
to Zoom R16/24, handled in create_standard_audio_quirk(). Let's move
this also to the new quirk_flags.

The txfr_quirk field was meant for aligning the transfer, and it's set
for certain devices in quirks-table.h. Now we can move that stuff
also to the new quirk_flags gracefully, and reduce the quirks-table.h
entries (that are exposed to module device table).
As the quirks-table.h entries are also with the name string override,
provide the corresponding entries to the usb_audio_names[] table,
too.

The devices that can have media-controller API entries are currently
specified via tables in quirks-table.h, as a part of descriptor
override. This can fit better to the new quirk_flags, as we just need
a matching with the given ID and create the MC entries accordingly.

As more and more device-specific workarounds came up and gathered in
various places, it becomes harder to manage. Now it's time to clean
up and collect workarounds more consistently and make them more easily
applicable.
This patch is the first step for that: a new field quirk_flags is
introduced in snd_usb_audio struct to contain the bit flags for
various device-specific quirks. Those are separate one from the
quirks in quirks-table.h; the quirks-table.h entries are for more
intrusive stuff that needs the descriptor override, while the new
quirk_flags is for easier ones that are tied with the vendor:product
IDs.
In this patch, as the first example, we convert the list of devices
and vendors to ignore GET_SAMPLE_RATE, formerly defined in
snb_usb_get_sample_rate_quirk().

The recent code refactoring made the mmap of continuous pages to be
done via the own helper snd_dma_continuous_mmap() with
remap_pfn_range(). There I overlooked that dmab->addr isn't set for
the allocation with SNDRV_DMA_TYPE_CONTINUOUS. This resulted always
in an error at mmap with this buffer type on the system such as
Intel SST Baytrail driver.
This patch fixes the regression by passing the correct address.

SoundWire mockup devices don't take part in the command/control

At the transition to the devres-managed card release, we've put the
check of double-free at trigger_card_release(). But this wasn't
enough, as the code path calls snd_card_free() again, and it would
lead to the doubly snd_card_free() calls.
Actually the v1 patch was correct to handle this, but I forgot that
corner case and moved the check to the more obvious place as I thought
it's clearer. But, as usual, devils live in details.
This patch corrects the check of the double-free to the right place,
with a bit more comments.

The transition to the managed PCM buffers allowed the dynamically
buffer allocation, while the driver code still assumes the fixed
preallocation buffer and sets up the DMA stuff at the open call.
This needs to be moved to hw_params after the buffer allocation and
setup. Also, the reference to the buffer address has to be corrected
to runtime->dma_addr.

Along with the transition to the managed PCM buffers, the driver now
accepts the dynamically allocated buffer, while it still kept the
reference to the old preallocated buffer address. This patch corrects
to the right reference via runtime->dma_addr.
(Although this might have been already buggy before the cleanup with
the managed buffer, let's put Fixes tag to point that; it's a corner
case, after all.)

PCM buffers might be allocated dynamically when the buffer
preallocation failed or a larger buffer is requested, and it's not
guaranteed that substream->dma_buffer points to the actually used
buffer. The driver needs to refer to substream->runtime->dma_addr
instead for the buffer address.

instead of substream->dma_buffer (and shouldn't use virt_to_phys).
Also, remove the line overriding runtime->dma_area superfluously,
which was already set up at the PCM buffer allocation.

When the component level pin control functions were added they for some
no longer obvious reason handled adding prefixing of widget names. This
meant that when the lack of prefix handling in the DAPM level pin
operations was fixed by ae4fc532244b3bb4d (ASoC: dapm: use component
prefix when checking widget names) the one device using the component
level API ended up with the prefix being applied twice, causing all
lookups to fail.
Fix this by removing the redundant prefixing from the component code,
which has the nice side effect of also making that code much simpler.

On some platforms with an external HDaudio codec, the DSDT reports the
presence of SoundWire devices. Pin-mux restrictions and board reworks
usually prevent coexistence between the two types of links, let's
prevent unnecessary operations from starting.
In the case of a single iDISP codec being detected, we still start the
links even if no SoundWire machine configuration was detected, so that
we can double-check what the hardware is and add the missing
configuration if applicable.

The indexes of the devices are described within the topology file, it is a
possibility that the topology encodes invalid indexes when DYNAMIC_MINORS
is not enabled in kernel:
#define SNDRV_MINOR_COMPRESS 2 /* 2 - 3 */
#define SNDRV_MINOR_HWDEP 4 /* 4 - 7 */
#define SNDRV_MINOR_RAWMIDI 8 /* 8 - 15 */
#define SNDRV_MINOR_PCM_PLAYBACK 16 /* 16 - 23 */
#define SNDRV_MINOR_PCM_CAPTURE 24 /* 24 - 31 */
If the topology assigns an index greater than 7 for PLAYBACK/CAPTURE PCM
then there will be minor number collision.
As an example:
card0 creates a capture PCM with index 10 -> minor = 34
card1 creates compress device with index 0 -> minor = 34
Card1 will fail to instantiate because the minor for the compress stream is
already taken.
To avoid seemingly mysterious issues with card creation, select the
DYNAMIC_MINORS when the topology is enabled.
The other option would be to try to do out of bound index checks in case of
DYNAMIC_MINOR is not enabled and do not even attempt to create the device
with failing the topology load.

MIDI Passthrough sequencer client is assigned always to the fixed
number 14, while it's wrongly documented in the comments as if 62,
which was an old number that was used during development. Fix all
those numbers.
