  11 commit 56df90b631fc027fe28b70d41352d820797239bb upstream.
  12
  13 Add patch for realtek codec in Lenovo B50-70 that fixes inverted
  14 internal microphone channel.
  15 Device IdeaPad Y410P has the same PCI SSID as Lenovo B50-70,
  16 but first one is about fix the noise and it didn't seem help in a
  17 later kernel version.
  18 So I replaced IdeaPad Y410P device description with B50-70 and apply
  19 inverted microphone fix.
