Subject: [PATCH AUTOSEL 5.6 138/606] ALSA: hda/realtek - Enable headset mic of ASUS GL503VM with ALC295

From: Chris Chiu <chiu@...lessm.com>

[ Upstream commit 9e43342b464f1de570a3ad8256ac77645749ef45 ]

The ASUS laptop GL503VM with ALC295 can't detect the headset microphone.
The headset microphone does not work until pin 0x19 is enabled for it.
