Subject: [65/93] ALSA: hda - Improved MacBook (Pro) 5,1 / 5,2 support

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

------------------

From: Alex Murray <murray.alex@...il.com>

commit a76221d47ef2b73ff16c0fef00a784026308ea02 upstream.

This patch adds support for automatically muting the speakers when headphones
are inserted, as well as relabelling the headphone widgets from the
non-standard "HP" to the standard "Headphone" for the mb5 model.
