Subject: [PATCH] ALSA: hda/realtek - Introduce polarity for micmute LED GPIO
Git-commit: dbd13179780555ecd3c992dea1222ca31920e892
Patch-mainline: v5.8-rc1
References: bsc#1111666

Currently mute LED and micmute LED share the same GPIO polarity.

So split the polarity for mute and micmute, in case they have different
polarities.
