It would've been easier for me if you had just posted a patch for the specfile
along with the patch you wanted to apply to the source.

Anyway, I had a look at it and I don't like it. You're hardcoding the driver
to v4l2. I think it'd be better to simply make the autodetection try v4l2
first. Also, is it necessary to change "/dev/radio" to "/dev/radio0"?

Please try the attached patch and see if it works for you.

Thanks and regards,
R.
