975cc02a90 ALSA: Replace the magic number 44 with const
The char arrays with size 44 are for the name string of
snd_ctl_elem_id.  Define the constant and replace the raw numbers with
it for clarifying better.

20a24225d8 ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at remove
As drvdata is cleared to NULL at probe failure or at removal by the
driver core, we don't have to call pci_set_drvdata(pci, NULL) any
longer in each driver.

The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
hda_intel.c.  Since this function itself releases the card instance,
we need to clear drvdata here as well, so that it won't be released
doubly in the remove callback.

167d0a11d5 ALSA: asihpi: add format support check in snd_card_asihpi_capture_formats
Some Asihpi formats are not supported or invalid, and their mapping to
ALSA format is set to -1.
Before performing the format conversion into ALSA bitwise formats,
add a consistency check for the requested format, as done in
snd_card_asihpi_playback_formats().

Compile tested only.

c38f62b08d ASoC: fixes for 3.4
A bunch of driver-specific fixes and one generic fix for the new support
 for platform DAPM contexts - we were picking the wrong default for the
 idle_bias_off setting which was meaning we weren't actually achieving
 any useful runtime PM on platform devices.
