Subject: RealTek Inverted Mic Patch

Hello,
I have hardware that suffers from an internal phase inverted mic that
isn't properly detected. Below is a patch that fixes the issue for my
particular hardware.
Pre patch alsa-info:

Incase you care. The patch is small. I don't know if you need any kind
of signed off/written by etc for something so small. In any case there
is no intellectual property in this at all. Feel free to do as you wish
with it. However including it in the kernel would make my life easier.
Thanks,
