Bug Description
Can confirm the bug on Lenovo g50-80.
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)?

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