I'd be happy to but whether cleaning it up would be benefitial or not
is a bit unclear.  We have 214 users of [un]register_chrdev_region()
and 118 users of [un]register_chrdev().  So, renaming the latter to,
say, create/destroy_chrdev() and make it take @baseminor and
@nr_minors should do it but I'm not quite sure whether it would worth
touching all those files.  Maybe it's better left as a mess like the
page allocation functions?
