v4l2: v4l2_camera_proxy: Check for null arg values in main ioctl handler
The ioctl handlers currently don't check if arg is null, so if it ever is, it will cause a segfault. Check that arg is null and return -EFAULT in the main vidioc ioctl handler. Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
