Mauro,
Could you pull these and send to stable as tagged per each patch. That 
patch set mainly increases sensitivity of the IT9135 chipset. It must be 
considered as a regression because IT9135 driver was replaced by AF9035 
(USB IF) + AF9033 (DVB-T demod) + IT913x (RF tuner) drivers starting 
from kernel 3.15.

I did a bunch of measurements with IT9135AX and IT9135BX devices. 
Sensitivity increases around 5 dB.

I measured -81dBm for IT9135BX and -79dBm for IT9135AX. Windows driver 
performs a little bit better still - for both chip versions around -82dBm.

I didn't noticed any sensitivity difference between old and new firmware.

regards
Antti
