From: Hui Wang hui.wang@canonical.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.
