Merge tag 'sound-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
- Fix a regression of USB-audio PCM assignment since 3.4
- A few VGA-switcheroo-related fixes for proper HDMI audio enablement
- Fixed the missing initializations of HD-audio verbs, which may have
resulted in various breakage
- Some driver-specific ASoC updates
- A few fixes for the dynamic PCM code
- The addition of pinctrl support for the i.MX audmux which didn't make
it into -rc1 due to cross tree dependency issues
- A few minor fixes in compress API codes
