From d4c0bb30d160b8bfea4d4d3a44bba55e40696bde Mon Sep 17 00:00:00 2001 From: Gustavo Maciel Dias Vieira Date: Tue, 24 Jan 2012 13:27:56 -0200 Subject: [PATCH] ALSA: hda: set mute led polarity for laptops with buggy BIOS based on SSID commit a6a600d10aaddf1da38053c4c6b64f50f56176e6 upstream. HP laptop models with buggy BIOS are apparently frequent, including machines with different codecs. Set the polarity of the mute led based on the SSID and include an entry for the HP Mini 110-3100.
