3.2-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kailang Yang <redacted> 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.
