v4l2-ctrls: must be able to enable/disable controlsctrl-enable
Controls can be dependent on the chosen input/output. So it has to be possible to enable or disable groups of controls, preventing them from being seen in the application. We need to allow duplicate controls as well so that two control handlers that both have the same control will still work. The first enabled control will win. And duplicate controls are always sorted based on when they were added (so the sorted list and the hash are both stable lists/hashes). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com>
