We've got a report that the runtime PM may make the codec the
unresponsive on AMD platforms.  Since the feature has been tested only
on the recent Intel platforms, it's safer to limit the support to such
devices for now.

This patch adds a new DCAPS bit flag indicating the runtime PM
support, and mark it for Intel controllers.

The Acer Aspire AO756 has an analog built-in mic on nid 0x1b and an
external mic on nid 0x19.  The BIOS doesn't set this up.

The mic detect on this Acer Aspire netbook and Acer C7 ChromeBook is
only valid when the headphone is plugged.  The detect circuit relies on
the tip detect switch being closed on the jack.  Tell hda_jack to ignore
the mic sense unless the headphones are plugged.

Introduce the concept of a "gated" jack.  The gated jack's pin sense
is
only valid when the "gating" jack is plugged.  This requires checking
the gating jack when the gated jack changes and re-checking the gated
jack when the gating jack is plugged/unplugged.

This allows handling of devices where the mic jack detect floats when
the headphone jack is unplugged.

When the bus reset is performed during the suspend/resume (including
the power-saving too), it calls snd_hda_suspend() and
snd_hda_resume() again, and deadlocks eventually.

For avoiding the recursive call, add a new flag indicating that the PM
is being performed, and don't go to the bus reset mode when it's on.

Commit 88a8516a (ALSA: usbaudio: implement USB autosuspend) added
autosuspend code to all files making up the snd-usb-audio driver.
However, midi.c is part of snd-usb-lib and is also used by other
drivers, not all of which support autosuspend.  Thus, calls to
usb_autopm_get_interface() could fail, and this unexpected error would
result in the MIDI output being completely unusable.

Make it work by ignoring the error that is expected with drivers that do
not support autosuspend.

The recent change for USB-audio disconnection race fixes introduced a
mutex deadlock again.  There is a circular dependency between
chip->shutdown_rwsem and pcm->open_mutex, depicted like below, when a
device is opened during the disconnection operation:

A. snd_usb_audio_disconnect() ->
     card.c::register_mutex ->
       chip->shutdown_rwsem (write) ->
         snd_card_disconnect() ->
           pcm.c::register_mutex ->
             pcm->open_mutex

B. snd_pcm_open() ->
     pcm->open_mutex ->
       snd_usb_pcm_open() ->
         chip->shutdown_rwsem (read)

Since the chip->shutdown_rwsem protection in the case A is required
only for turning on the chip->shutdown flag and it doesn't have to be
taken for the whole operation, we can reduce its window in
snd_usb_audio_disconnect().

Probing this device currently fails in snd_usb_audio_probe() because
the call to snd_usb_create_mixer() fails.  This is due to unknown or
non-standard interface descriptor subtypes in parse_audio_unit():

  usbaudio: unit 51: unexpected type 0x09
  snd-usb-audio: probe of 1-8:1.0 failed with error -5

Some people are working around this by recompiling usb-audio with the
call to snd_usb_create_mixer() commented out.  It would be nice to
avoid that.

While the best idea would be to look into the mixer creation failure,
a reasonable short-term solution is to use quirks to only probe the
trouble-free interfaces.  This allows audio and MIDI interfaces to be
used without any obvious issues.

Interface 0 is the main one to ignore.  It contains lots of
control-fu, including the unexpected interface descriptor subtypes.
Interface 5 is for firmware updates and I'm not sure how to get
support for this.  Interface 3 is some sort of control interface that
I don't understand:

    Interface Descriptor:
      bLength                 9
      bDescriptorType         4
      bInterfaceNumber        3

The RayDAT reports the sync status of its inputs in consecutive bit
positions, so all we do in hdspm_s1_sync_check is to iterate over idx:

    status = hdspm_read(hdspm, HDSPM_RD_STATUS_1);

    lock = (status & (0x1<<idx)) ? 1 : 0;
    sync = (status & (0x100<<idx)) ? 1 : 0;

The index is given in kcontrol->private_value:

    HDSPM_SYNC_CHECK("WC SyncCheck", 0),
    HDSPM_SYNC_CHECK("AES SyncCheck", 1),
    HDSPM_SYNC_CHECK("SPDIF SyncCheck", 2),
    HDSPM_SYNC_CHECK("ADAT1 SyncCheck", 3),

In via_auto_fill_adc_nids(), the parser tries to fill dac_nids[] at
the point of the current line-out (i).  When no valid path is found
for this output, this results in dac = 0, thus it creates a hole in
dac_nids[].  This confuses is_empty_dac() and trims the detected DAC
in later reference.
