[GIT PULL] sound fixes

[Takashi Iwai <tiwai@suse.de>]

Linus,

please pull misc sound fixes for v2.6.31-rc7 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git fix/misc

One fix for sound/core/pcm_lib.c looks non-trivial, but actually it's
also a good clean-up.  The others are trivial indeed.


Thanks!

Takashi
