Chasing niov->owner is true, but I don't see another dereference you're
talking about? net_devmem_iov_binding does container_of to get from
area to the binding (and the area is the first member of the binding,
so it is a already a nop). And IIRC, iou has a similar arrangement.
So I'd vote to keep things as is unless you explain what I'm missing.
