These two functions were added two years ago in commit 4805608a ("ASoC: dapm -
Add methods to retrieve snd_card and soc_card from dapm context.") but have
remained unused so far. Considering that the dapm context actually has a direct
pointer to the card the functions also seem to be unnecessary. E.g. the
expressions 'dapm_get_soc_card(dapm)' and 'dapm->card' yield the same result.

There is no need to use a normal per-CPU workqueue for delayed power downs

Commit 8f898e92 removed the redundant
reads of bInterfaceProtocol from the descriptors, but introduced a
regression to devices with quirks of type QUIRK_AUDIO_FIXED_ENDPOINT,
since fp->protocol is not set in setup process.

As a consequence, audio streams would not get initialized, as the
following logs show:

[   48.923043] setting usb interface 3:1
[   48.923056] Creating new capture data endpoint #81
[   48.923484] 4:3:1: cannot set freq 48000 to ep 0x81

This patch sets fp->protocol in create_fixed_stream_quirk() and
resolves the regression.

ad1884_fixup_hp_eapd() tries to set the NID for controlling the
speaker EAPD from the pin configuration.  But the current code can't
work expectedly since it sets spec->eapd_nid before calling the
generic parser where the autocfg pins are set up.

This patch changes the function to set spec->eapd_nid after the
generic parser call while it sets vmaster hook unconditionally.  The
spec->eapd_nid check is moved in the hook function itself instead.

Mostly the mxs system design uses saif0 mclk output as the clock source
of codec.  Since the mclk is implemented as a general divider with the

provdier, clk_get() call in codec driver probe function will just work.

snd_card_register() registers all devices newly added since the last
call.  However, the playback/capture streams are handled as one ALSA
device, so the second /dev device will not be registered if the PCM
streams are added in two steps.

QUIRK_AUTODETECT caused the probe callback to be called once for each
interface, which triggered this problem.  Work around this by handling
this like the composite quirk, i.e., autodetecting all other interfaces
that might be used for PCM or MIDI.
