Feel free to do that. Actually, I just tried it about 2 hours ago. But I 
failed, since there callbacks given as a param for tuner attach and it 
is wrong. There is frontend callback defined just for that. Look example 
from some Xceive tuners also hd29l2 demod driver contains one example. 
Use git grep DVB_FRONTEND_COMPONENT_ drivers/media/ to see all those 
existing callbacks.

struct dvb_frontend *fc0011_attach(struct dvb_frontend *fe, struct 
i2c_adapter *i2c, u8 i2c_address, int (*tuner_reset)(unsigned long, 
unsigned long),unsigned long tuner_reset_arg0,unsigned long 
tuner_reset_arg1)

My short term plans are now
* fix af9033 IF freq control (now Zero-IF only)
* change firmware download to use new firmware syntax
* dual tuner support
* check if IT9035 is enough similar (My personal suspicion is that 
integrated tuner is only main difference, whilst USB-interface and demod 
are same. But someone has told that it is quite different design though.)
* implement SNR, BER and USB counters
* implement remote controller
