When you change this, you should call __v4l2_ctrl_modify_range to modify the
range of the controls that depend on this.

You can make a patch '13/12' for this or post a v9 for this patch. I would like to
see this implemented. It's one of those things that never gets implemented if you
don't address this now.

It shouldn't be difficult to do.

Regards,

Hans
