Hi,
First of all many thanks for working on this! Note I've also taken
a quick look at the original patch with the actual implementation and that looks
good. I'm replying here because in my mind the API is the most interesting
thing to discuss.

Hi,
Overall this looks good, but some of the code, for example the set/get freq and
get/set tuner stuff seems to be a 1 on 1 copy of code from v4l2-ctrl, please
factor this out into a common file which can be shared between both
utilities (I think Hans V's recent work on splitting v4l2-ctl into m

Thanks for the patch, I've taken a look at this, and the way the pac207's

I saw you've pulled in my tree, I assume this is for Linus for 2.6.32, I hope
