Well I'm not too hot on kernel development, in particular I really don't
understand the frontend stuff and also all the internal i2c communication
bits! I've written i2c bit banging protocol stuff directly before but this is
all too weird...
That said if its just delaying unloading dvb core stuff until ref count is
zero (rather than directly unloading on unregister) then I'll have a go. I'll
have to see what the T2 driver's strategy is. I'll take a look this W/E.
