[alsa-devel] [PATCH] Fix for Lenovo B50-70 inverted internal microphone bug.

[Michał Wadowski]

Add patch for realtek codec in Lenovo B50-70 that fixes inverted internal microphone channel.
Device IdeaPad Y410P has the same PCI SSID as Lenovo B50-70,
but first one is about fix the noise and it didn't seem help in a later kernel version.
So I replaced IdeaPad Y410P device description with B50-70 and apply inverted microphone fix.
