* Much of this code is derived from the cx88 and sa7134 drivers, which
* were in turn derived from the bt87x driver. The original work was by
* Gerd Knorr; more recently the code was enhanced by Mauro Carvalho Chehab,
* Hans Verkuil, Andy Walls and many others. Their work is gratefully
* acknowledged. Full credit goes to them - any problems within this code
