Subject: ALSA: hda - Fix default polarity of mute-LED GPIO on 92HD83x/88x codecs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dce17d4ff366230aeeaaf42512bba3711243cf1c;p=linux-beck.git

ALSA: hda - Fix default polarity of mute-LED GPIO on 92HD83x/88x codecs

The previous commit caused a regression on HP laptops with 92HD83x/88x
codecs.  The default polarity of mute-LED GPIO is inverted on these
devices.
