The LP5523 has 3 engines which are used for running LED patterns. These engines should be off while unloading the driver. Obviously, LP5523 platform data are used for releasing the resource such like enable()/release_resource(), but these are not mandatory. Therefore this patch is required without the platform data dependency.
