the whole point of using *byname() is for the driver to not care about
the order of the resources. So if driver has to provided an ordered list
of names, what's the benefit ? Sounds really stupid to provide an
ordered list of names to an ordered list of resources, just to use
*byname() instead of just assuming the list of resources is already
ordered.
