3.4-stable review patch. If anyone has any objections, please let me know.


From: David Henningsson <david.henningsson@xxxxxxxxxxxxx>

commit f7f4b2322bf7b8c5929b7eb5a667091f32592580 upstream.

This caused the internal speaker to mute itself because it was
present, which happened after powersave.
It was found on Dell XPS 15 (L502x), ALC665.
