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. Reference: Novell bnc#578190 https://bugzilla.novell.com/show_bug.cgi?id=578190 Signed-off-by: Takashi Iwai <tiwai@suse.de>
