Subject: [PATCH 4.19 60/91] ALSA: hda/realtek - Headphone Mic cant record after S3

From: Kailang Yang <kailang@...ltek.com>

commit d07a9a4f66e944fcc900812cbc2f6817bde6a43d upstream.

Dell headset mode platform with ALC236.
It doesn't recording after system resume from S3.
S3 mode was deep. s2idle was not has this issue.
S3 deep will cut of codec power. So, the register will back to default
after resume back.
This patch will solve this issue.
