This looks like a reasonable fix but it doesn't apply against current
kernels.  Could you please regenerate it against

  git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git for-2.6.33

Please do also remember to CC the maintainers of the relevant kernel
subsystems on submitted patches - scripts/get_maintainer.pl is helpful
here.  Things only sent to mailing lists sometimes get lost due to the
volume.
