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"
