Merge tag 'sound-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "This batch contains a few USB audio fixes, a couple of HD-audio
  quirks, various small ASoC driver fixes in addition to an ASoC core
  fix that may lead to memory corruption.

  Unfortunately slightly more volume than the previous pull request, but
  all are reasonable regression fixes"
