[PATCH] ALSA: hda/realtek: Fix mic mute LED for the HP Spectre x360 14

From: Johnathon Clark
Date: Wed Oct 20 2021 - 09:13:22 EST


On the 'HP Spectre x360 Convertible 14-ea0xx' the microphone mute led is
controlled by GPIO 0x04. The speaker mute LED does not seem to be
exposed by GPIO and is there not set.
