Also, device names can also be ridiculously long.  I really just don't
think logging the name instead of major:minor is a great idea... but I'm
open to target authors electing to log it _in addition to_
dm_device_name() -- but I wouldn't want to go as far as imposing that
constraint with code...

Or would I? ;)

Create dm_pretty_device_name() that logs: "major:minor (name)" ?
