Add the appropriate quirk to indicate the Lenovo G50-80 has a stereo mic input where one channel has reverse polarity.

Alsa-hda-dkms package doesn't help (there is no "Inverted Internal Mic" entry in alsamixer after reboot). Removed alsa-hda-dkms and tried "option snd-hda-intel model=auto" but it doesn't help. Workaround "mute right channel" works but can it be fixed permanently (I don't want to manually mute right mic channel every time I use skype)?
