Contributing to rtl-sdr (fc0012)

Hi! I'm just wondering what the best way to be able to contribute code into the rtl-sdr project is? I've added support for the FC0012 tuner (based on the dvb driver and cleaned up some), and would much rather contribute directly rather than fork it just for the sake of the stuff I write. There's a diff here: https://gist.github.com/2171926 against rtl-sdr a few days back. I've got a couple of fixes that aren't in that patch still to upload (like setting GPIO6 to flip the V/U band filter. Oops.) Cheers, David
