Bill, Your question also did not specify if this was a driver for an analog (V4L2) or DTV (DVB) capture unit. Hans' comments regarding v4l2_device/v4l2_subdev currently only apply to analog capture units or the analog side of hybrid capture units. If you have a DTV-only capture unit, the v4l2_device/v4l2_subdevice framework doesn't apply at present. AFAICT, the saa7134 and cx18 drivers both have code to deal with hybrid analog/DTV units.
