[PATCH] ALSA: hda/realtek: Add micmute quirk to Acer Nitro AN515-58

[Dirga Yuza]

The Acer Nitro AN515-58 uses GPIO 4 in active-low configuration to
control the mic-mute LED. This patch adds a fixup to register the LED
classdev and associate it with the mic-mute trigger, while chaining to
the existing headset mic fixup.
