Subject[PATCH] ALSA: hda/realtek: Enable HP amp and mute LED on HP Folio 9480m
Date
This laptop needs GPIO4 pulled high to enable the headphone amplifier,
and has a mute LED on GPIO3. I modelled the patch on the existing
GPIO4 code which pulls the line low for the same purpose; this time,
the HP amp line is pulled high.
