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

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

From: Takashi Iwai <tiwai@suse.de>

commit 7a3e6107f94344e65c35bfe62de6c096a7b48965 upstream.

The only EAPD on AD1986A is on NID 0x1b where usually the speaker.
But this doesn't control only the speaker amp but may influence on all
outputs, e.g. Lenovo N100 laptop seems to have this issue.
