Please try to avoid this sort of misdirected yelling, it's not helping
anything to complain that people are following the recommendations of
the maintainer or to demand that this somehow gets hacked around in
arch/ when we're trying to convince all the architectures to get their
drivers merged into subsystem trees so they're reviewed by the subsystem
maintainers.

If you have some examples of better practice for serial device
registration that you'd like to identify that'd be helpful, but what
you're doing here is making disparaging remarks and telling people to
adopt bad practices because someone else made a mistake a decade ago.
That is how problems like this get created in the first place.

Then you need to convince Greg of that.  The most recent set of patches
are exactly what he asked for.
