Subject: [GIT PULL] sound fixes for 2.6.35-rc1
Linus,
please pull ALSA updates for v2.6.35-rc1 from:
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git for-linus
A large part of changes are small updates/fixes of refactored
USB-audio stack and a few updates of asihpi driver. In addition, a
couple of fixes for USB caiaq, and other misc trivial fixes here and
there.
Thanks!
Takashi
