Ok, devices (hw) might not be removable - that also the case for uarts
builtin some SoCs, or the good old PC w/ 8250. But does that also mean
that the driver should not be removable ?

IMHO, even if that's the case, it's still inconsistent. The driver then
shouldn't support a remove at all (or even builtin only), not just
incomplete remove.

By the way: do we have some people who have those old hw and could test?
Should we (try to) create some ? Perhaps some "tester" entry in
MAINTAINERS file ? (I could ask around several people who might have
lots of old / rare hardware.)

hmm, looks like a pipeline stall ;-)
why not collecting in a separate branch, which later gets rebased to
mainline when rc is out ?

So it's also a fixed schedule for your other work. Understood.

It seems that this workflow can confuse people. Few days ago, somebody
became nervous about missing reactions on patches. Your autoresponder
worked for me, but maybe not for everybody.
