[GIT PULL] ALSA fixes

[Takashi Iwai <tiwai@suse.de>]

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
