Subject: ALSA: hda/realtek - Apply the coef-setup only to ALC269VB
From: Kailang Yang <[email protected]>
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.
