Hi,

The quick review by crop@freenode was:

"I quick check it and didnt like much since it is not plitted logically 
correct, as usb-bridge, demod and tuner. now all are rather much one big 
blob".

so I guess you have to split it into pieces in a way other dvb drivers already 
in kernel tree are done. Unfortunately I don't know which existing driver is 
the best example on how to do things.

ps. are the IT9135 docs available anywhere?

ps2. on current linus 3.1 git + your 2 patches it is at least detected (cannot 
test more yet - no dbv-t signal here; it's to be available in incoming days)
