From: Laurent Pinchart <laurent.pinchart+renesas@xxxxxxxxxxxxxxxx>
Let userspace specify a request ID when getting or setting formats. The
support is limited to the multi-planar API at the moment, extending it
to the single-planar API is possible if needed.
>From a userspace point of view the API change is also minimized and
doesn't require any new ioctl.
