[GIT PULL] ALSA fixes #2 for 2.6.26-rc3

[Takashi Iwai]

Hi Linus,

please pull ALSA updates for 2.6.26-rc3 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git for-linus

This contains another snd-pcsp fix slipped from the last pull request,
and two trivial fixes for specific HD-audio models.

Thanks!

Takashi
