[media] radio-gemtek-pci: remove duplicate driver
The radio-gemtek-pci driver is for the same hardware as the radio-maxiradio driver which uses the same GemTek PR103 and tea5757 combination and the two drivers are identical. I chose the maxiradio over the gemtek-pci driver since the maxiradio has support for mono/stereo detection. Tested with my gemtek-pci card.

Choose Y here if you have this PCI FM radio card.

In order to control your radio card, you will need to use programs

that are compatible with the Video for Linux API. Information on

this API and pointers to "v4l" programs may be found at
