Hi Volokh! First of all, thanks for the patch!
Everything looks OK, except for one thing, see below...

It will simplify it and since I am in the process myself of converting all drivers to use the control framework it would be very helpful indeed. See Documentation/video4linux/v4l2-controls.txt for more information. A simple driver like drivers/media/video/wm8775.c will provide a good example for you. This driver really needs work to get it out of staging. An initial attempt was made back in 2009 (http://www.spinics.net/lists/linux-media/msg10252.html), but it was never finished, unfortunately.
