In most of the cases (and that includes floppy.c) unregister_disk() would
be invoked by unregister_blkdev().  The only exception (back then, now
we probably have more) would be SCSI.  That stuff got frozen in the middle
of a merge by devfs inclusion (2.3.46 or so).  Right now register_disk()
is no-op for partitionless devices.
