Sorry, I said that the wrong way round due to trying to reply quickly -
the card would be the thing that moves since that's the thing that
actually does the suspend but we've *no* idea which device we need to
move it after. Since all the function does is a direct move after or
before a single device all we can do is pick one and pray that it's the
right device.
