One thing you should do is to run the v4l2-compliance utility. Available
here: http://git.linuxtv.org/cgit.cgi/v4l-utils.git/

Compile from the git repo to ensure you have the latest version.

Run as 'v4l2-compliance -s' (-s starts streaming tests as well and it
assumes you have a valid input signal).

The driver shouldn't give any failures. When you post the actual patch,
then make sure you also paste in the output of 'v4l2-compliance -s' as
I'd like to see what it says.

Mail if you have any questions about the v4l2-compliance output. The failure
messages expect you to look at the v4l2-compliance source code as well,
but even than it is not always clear what is going on.
