Sorry, I've been offline in the last 15 days, so I did not see your patch.
I think that it's ok in principle, but I'd like to have a better look at
it, and to test it on different distributions (to check if VIDIOC_S_PARM
is always available - I seem to remember some problems, but I might be
wrong) and with some different devices.

But I still have more than 700 emails to read and answer... Please give
me some days (if you do not hear anything before wednesday, send me a
private reminder).
