How can I create a patch?

How can I create a patch?

[xwang1976]

Hi to all,
I've a usb hybrid tuner which does not work with the main v4l driver.
I've found a way to use it modifying some lines in the em28xx-dvb.c and 
em28xx-cards.c files (thanks to Dainius Ridzevicius).
Can someone explain me how to create a diff between the main v4l
driver and the patched version so that I can share it in order to have 
it merged upstream?
Thank you,
Xwang
