From: Hans Verkuil <hans.verkuil@xxxxxxxxx> Add a 'bool from_other_dev' argument: set to true if the two handlers refer to different devices (e.g. it is true when inheriting controls from a subdev into a main v4l2 bridge driver). This will be used later when implementing support for the request API since we need to skip such controls. TODO: check drivers/staging/media/imx/imx-media-fim.c change.
