[Ben Hutchings]

3.16.35-rc1 review patch.  If anyone has any objections, please let me know.

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

From: Bobi Mihalca <bobbymihalca@xxxxxxxxxxxx>

commit 9d4dc5840f93bcb002fa311693349deae7702bc5 upstream.

For reducing the noise from the headphone output on ASUS N750JV,
call the existing fixup, alc_fixup_auto_mute_via_amp(), additionally.
