Subject: [PATCH 4/6] sound/pci/hda: Remove CD control from model=benq for
 CX20549

The ID used for detection of the BenQ R55E actually identifies the
Quana TW3 ODM design, which is also used for the Gigabyte W551 laptop
series. Schematics on the internet clearly indicate that the "Port C"
(analog input connected to record source #4 and mixer input #4) is
unconnected.
