| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
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.
