Subject: [PATCH] [92/223] ALSA: hda: Use BIOS auto-parsing instead of existing model quirk for MEDION MD2

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Daniel T Chen <crimsun@...ntu.com>

commit ac70eb1305d5a81efd1e32327d7e79be15a63a5a upstream.

BugLink: https://launchpad.net/bugs/682199

A 2.6.35 (Ubuntu Maverick) user, burningphantom1, reported a regression
in audio: playback was inaudible through both speakers and headphones.
In commit 272a527c04 of sound-2.6.git, a new model was added with this
machine's PCI SSID.  Fortunately, it is now sufficient to use the auto
model for BIOS auto-parsing instead of the existing quirk.

Playback, capture, and jack sense were verified working for both
2.6.35 and the alsa-driver snapshot from 2010-11-27 when model=auto is
used.
