I was under the impression that MODULE_ALIAS
was something people put in to make platforms using
udev behave better by default, e.g. autoprobing these
devices better (on coldplug for "platform:*").

For example:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4f46d6e7e5ffbce0ee1d1a80767fdf45e56cc863

But I might have got it all wrong :/
