I examined the lgdt3303  driver to see if it makes sense to 
merge it with the lgdt3302 driver. I don't have a spec 
sheet for the 3303 chip so I may have made some errors in 
my examination. It may be pin compatible, but it is not 
software compatible.

The lgdt3303 is connected to a different PCI interface chip 
than the lgdt3302.

Overall the driver structure is nearly identical. Different 
registers are used by the 3303 in a lot of places. Some of 
the registers are read only in the 3302 and writable in the 
3303. A number of new registers are set in the 3303. The 
drivers could be combined, but I am not sure how beneficial 
that would be.

There is an unusual way of setting up the tuner.

I do not recommend merging the two drivers at this time.
