Subject: [PATCH 5.15 032/917] ALSA: hda/realtek: Fix mic mute LED for the HP Spectre x360 14

From: Johnathon Clark <john.clark@...tab.net>

commit 5fc462c3aaad601d5089fd5588a5799896a6937d upstream.

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.

[ a slight coding-style fix by tiwai ]
