2.6.32-stable review patch. If anyone has any objections, please let us know.

From: Daniel T Chen <crimsun@ubuntu.com>
commit 0b587fc4d35afb1bc0fc3d890084bb14c78372dc upstream.
BugLink: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4792
Cristian reported that these models have really bad sound above 6 dB and proposed the original patch. I've updated the comment to reflect this change.
