Note, manually specifying the MODULE_ALIAS is only really ever done for
platform drivers today (and I would argue we need to fix that up),
otherwise the use of MODULE_DEVICE_TABLE() should really really be used
instead of having to manually specify aliases.

And why would a module alias be needed for new (i.e. rust) code anyway?
You aren't trying to do any backwards-compatibility stuff yet :)

Or is this just for a platform driver?  It's hard to review
infrastructure changes without seeing any real users :(
