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

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

From: Chris Chiu <chiu@endlessm.com>

commit d8ae458eeca9ed686e09a1b894867cb91fc4c1cb upstream.

The known ALC256_FIXUP_ASUS_MIC fixup can fix the headphone jack
sensing and enable use of the internal microphone on this laptop
X542UN. However, it's ALC294 so create a new fixup named
ALC294_FIXUP_ASUS_MIC to avoid confusion.
