[ 02/41] ALSA: hda/realtek - Apply the coef-setup only to ALC269VB

From: Greg KH
Date: Fri Mar 16 2012 - 19:51:32 EST


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

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

From: Kailang Yang <kailang@xxxxxxxxxxx>

commit 526af6eb4dc71302f59806e2ccac7793963a7fe0 upstream.

The coef setup in alc269_fill_coef() was designed only for ALC269VB
model, and this has some bad effects for other ALC269 variants, such
as turning off the external mic input. Apply it only to ALC269VB.
