Subject: [GIT PULL] ALSA fixes
Linus,
please pull ALSA updates for 2.6.28-rc5 from:
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git for-linus
This contains fixes for bugs with STAC/IDT HD-audio codecs, typically
hitting Dell laptops.
Thanks!
Takashi

Takashi Iwai (3):
ALSA: hda - Add missing analog-mux mixer creation for STAC9200
ALSA: hda - Fix input pin initialization for STAC/IDT codecs
ALSA: hda - Fix IDT/STAC multiple HP detection
