The check for infoframe transmit status in hdmi_infoframe_uptodate()
makes the assumption that packet buffer index is set to zero.
Align code with specification and explicitly set the index before
AC_VERB_GET_HDMI_DIP_XMIT. The packet index setting affects both
DIP-Data and DIP-XmitCtrl verbs.
There are no known cases where the old implementation has caused driver
to work incorrectly. This change is purely based on code review against
the specification (HDA spec rev1.0a).

The current channel-map control implementation in USB-audio driver may
lead to an error message like
"control 3:0:0:Playback Channel Map:0: access overflow"
when CONFIG_SND_CTL_VALIDATION is set. It's because the chmap get
callback clears the whole array no matter which count is set, and
rather the false-positive detection.
This patch fixes the problem by clearing only the needed array range
at usb_chmap_ctl_get().

The debug prints from patch_hdmi.c are not aligned with HDA common code
in hda_codec.c nor with other HDA codec drivers.
To align with rest of the codebase, use hexadecimal formatting whenever
printing value of a HDA NID. Also refer to NIDs with capital letters in
traces as is done other modules. This presentation is also aligned with
the formatting used in HDA codec procfs entry.

A problem exists in enabling silent stream when connection type is
DisplayPort. Silent stream programming is completed when a new DP
receiver is connected, but infoframe transmission does not actually
start until PCM is opened for the first time. This can result in audible
gap of multiple seconds. This only affects the first PCM open.
Fix the issue by properly assigning a converter to the silent stream,
and modifying the required stream ID programming sequence.
This change only affects Intel display audio codecs.

It seems that the HD-audio clear and reconfig sysfs don't work any
longer after the recent driver core change. There are multiple issues
around that: the linked list corruption and the dead device handling.
The former issue is fixed by another patch for the driver core itself,
while the latter patch needs to be addressed in HD-audio side.
This patch corresponds to the latter, it recovers those broken
functions by replacing the device detach and attach actions with the
standard core API functions, which are almost equivalent with unbind
and bind actions.

The snd_seq_queue struct contains various flags in the bit fields.
Those are categorized to two different use cases, both of which are
protected by different spinlocks. That implies that there are still
potential risks of the bad operations for bit fields by concurrent
accesses.
For addressing the problem, this patch rearranges those flags to be
a standard bool instead of a bit field.

This change could fix 2 issues on this machine:
- the bass speaker's output volume can't be adjusted, that is because
the bass speaker is routed to the DAC (Nid 0x6) which has no volume
control.
- after plugging a headset with vol+, vol- and pause buttons on it,
press those buttons, nothing happens, this means those buttons
don't work at all. This machine has alc287 codec, need to add the
codec id to the disable/enable_headset_jack_key(), then the headset
button could work.
The quirk of ALC285_FIXUP_THINKPAD_HEADSET_JACK could fix both of these
2 issues.

The check for the FW_FEATURE_PS3_LV1 firmware feature is already performed
in ps3_system_bus_init() before registering the driver. So if the probe
function is actually used, this feature is already known to be available.
The check for the match id is also superfluous; the condition is always
true because the bus' match function (ps3_system_bus_match()) only
considers this driver for devices having:
dev->match_id == snd_ps3_bus_driver_info.match_id.

ASUS Zephyrus G14 has two speaker pins, and the auto-parser tries to
assign an individual DAC to each pin as much as possible.
Unfortunately the third DAC has no volume control unlike the two DACs,
and this resulted in the inconsistent speaker volumes.
As a workaround, wire both speaker pins to the same DAC by modifying
the existing quirk (ALC289_FIXUP_ASUS_GA401) applied to this device.
Since this quirk entry is chained by another, we need to avoid
applying the DAC assignment change for it. Luckily, there is another
quirk entry (ALC289_FIXUP_ASUS_GA502) doing the very same thing, so we
can chain to the GA502 quirk instead.
Note that this patch uses a new flag of the generic parser,
obey_preferred_dacs, for enforcing the DACs.

The generic parser accepts the preferred_dacs[] pairs as a hint for
assigning a DAC to each pin, but this hint doesn't work always
effectively. Currently it's merely a secondary choice after the trial
with the path index failed. This made sometimes it difficult to
assign DACs without mimicking the connection list and/or the badness
table.
This patch adds a new flag, obey_preferred_dacs, that changes the
behavior of the parser. As its name stands, the parser obeys the
given preferred_dacs[] pairs by skipping the path index matching and
giving a high penalty if no DAC is assigned by the pairs. This mode
will help for assigning the fixed DACs forcibly from the codec
driver.

With a stream with low bitrate, user can't pause or resume the stream
near the end of the stream because current ALSA doesn't allow it.
If the stream has very low bitrate enough to store whole stream into
the buffer, user can't do anything except stop the stream and then
restart it from the first because most of applications call draining
after sending last frame to the kernel.
If pause, resume are allowed during draining, user experience can be
enhanced.
To prevent malfunction in HW drivers which don't support pause
during draining, pause during draining will only work if HW driver
enable this feature explicitly by calling
snd_compr_use_pause_in_draining().

This patch extends the implicit feedback mode parser code to check the
description more generically, so that the quirk entries can be added
without the explicit EP and interface numbers. The search is done for
the next and the previous interface of the given altset, and if both
entries are ASYNC mode and the direction matches, it just takes as the
sync endpoint. The generic parser is applicable only for the playback
stream.
As of now, only a few M-Audio devices have been converted to use this
mode.

The code dealing with the implicit feedback mode grew recently, and
it's becoming messy. As we receive more and more devices that need
the similar handling, it's better to be processed through a table
instead of the open code.
This patch moves the code that is relevant with parsing the implicit
feedback mode and some helpers into another file, implicit.c. The
detection and the setup of the implicit feedback sync EPs are
rewritten to use the ID/class matching table instead.
There should be no functional changes.

The capture stream of BOSS GT-001 seems always requiring to be tied
with the playback stream. OTOH, the playback stream of this device
doesn't seem working in the implicit fb mode, per se, since the
playback must be running before the capture stream.
This patch tries to address the points above:
- Avoid the implicit fb mode for the playback
- Set up a fake sync EP for the capture stream with the hard-coded
playback stream using the implicit fb mode

Now the sync endpoints have been parsed at the beginning and won't be
changed dynamically, let's show them in the proc outputs for helping
debugging.

Just for consistency, use unsigned char for iface and altsetting in
allover places. Also rearrange the field positions of
snd_usb_endpiont and tidy up with some comments.

Follow the inclusive terminology, just replace sync_master/sync_slave
with sync_source/sync_sink. It's also a bit clearer from its meaning,
too.

There are multiple places in format.c performing the similar code for
setting the rate_min, rate_max and rates fields. This patch unifies
those in a helper function and calls it at the end of the parser phase
so that all rate_table entries have been already determined.
No functional changes, just a minor code refactoring.
