Hans Verkuil 34a6b7d093 [media] v4l2-ctrls: add a filter function to v4l2_ctrl_add_handler 
With a filter function you can control more precisely which controls
are added. This is useful in particular for radio device nodes for
combined TV/Radio cards where you want to show just the radio-specific
controls and not controls like brightness.
