Subject: [PATCH 4.1 49/78] ALSA: hda - Fix the white noise on Dell laptop

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

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

From: Woodrow Shen <woodrow.shen@...onical.com>

commit 7ccb0a9917a511de1d5f92980f26885484d9a914 upstream.

Dell laptop causes the white noise by login screen and headphone,
and the fixup function ALC292_FIXUP_DISABLE_AAMIX can eliminate this
noise.
