Subject: [PATCH 4.19 014/131] ALSA: hda/realtek: Enable mute LED on an HP system

From: Kai-Heng Feng <kai.heng.feng@...onical.com>

[ Upstream commit f5a88b0accc24c4a9021247d7a3124f90aa4c586 ]

The system in question uses ALC285, and it uses GPIO 0x04 to control its
mute LED.

The mic mute LED can be controlled by GPIO 0x01, however the system uses
DMIC so we should use that to control mic mute LED.
