From 5bdaaada16363d64e10ae081755d1a8d392429f2 Mon Sep 17 00:00:00 2001 From: Vitaliy Kulikov Date: Wed, 4 Nov 2009 07:57:45 +0100 Subject: ALSA: hda - Enable GPIO control for mute LED on HP systems This patch enables GPIO to control mute LED indicator on the HP systems with the special string in BIOS and applies it with the correct polarity on HP B-series systems. It also restores configuration of the pin intended as the second Headphone on HP B-series systems but configured as something else in the BIOS to pass MS DTM.
