Subject: [PATCH] ALSA: hda/realtek - Enable micmute LED on and HP system
Git-commit: 3e0650ab26e2010ee312311612e40e076ed1feca
Patch-mainline: v5.8-rc1
References: bsc#1111666
Though the system uses DMIC, headset mic still uses the HDA, let's use
GPIO 0x1 to control the micmute LED.
The micmute LED GPIO has a different polarity to the mute LED GPIO, we
can use the newly added micmute_led_polarity to indicate that.
