Subject: [PATCH 4.13 15/33] ALSA: hda - fix headset mic problem for Dell machines with alc274

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

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

From: Hui Wang <hui.wang@...onical.com>

commit 75ee94b20b46459e3d29f5ac2c3af3cebdeef777 upstream.

Confirmed with Kailang of Realtek, the pin 0x19 is for Headset Mic, and
the pin 0x1a is for Headphone Mic, he suggested to apply
ALC269_FIXUP_DELL1_MIC_NO_PRESENCE to fix this problem. And we
verified applying this FIXUP can fix this problem.
