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

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

From: Jian-Hong Pan <jian-h...@endlessm.com>

commit e1037354a0a75acdea2b27043c0a371ed85cf262 upstream.

The ASUS laptop X441MB and X705FD with ALC256 cannot detect the headset
MIC until ALC256_FIXUP_ASUS_MIC_NO_PRESENCE quirk applied.
