video_unregister_device() calls device_unregister(), which calls put_device(), which calls kobject_put(), and if this is the last reference then kobject_release() is called, which calls kobject_cleanup(), which calls ktype's release method which happens to be device_release() in this case, which calls dev->release(), which happens to be v4l2_device_release() in this case, which calls vdev->release(), which happens to be video_device_release(). But video_device_release() is called explicitly both in error recovery path of s5p_jpeg_probe() and in s5p_jpeg_remove(). The pointers in question are not nullified between the two calls, so this is harmful. This patch fixes the driver so that video_device_release() is not called twice for the same object.
