Prof 7500 linux kernel driver mods

This will modify the stv0900 ko so that it reports back the tuned information when FE_GET_PROPERTY is called. The stock ko doesnt do this, because the hardware using blindsearch() can lock such a wide range its nice to know the actual details of what it locked onto.

the driver will do search +/-5mhz, +/- 10000SR, auto fec, auto inversion, auto modulation, auto system, auto pilot/rolloff

also if you set any fec at all that isnt auto, it will use warmstart() insted of blindsearch(), this will speed up the locking of signal. it'll still do autofec, it just uses the fec as a switch to turn blindsearch() on/off
