[patch 08/86] ALSA: hda - Disable dynamic-power control for VIA as default

From: Greg KH
Date: Fri Feb 10 2012 - 18:17:41 EST


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

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

From: Takashi Iwai <tiwai@xxxxxxx>

commit b5bcc189401c815988b7dd37611fc56f40c9139d upstream.

Since the dynamic pin power-control and the analog low-current mode
may lead to pop-noise, it's safer to set it off as default.
