I'm not really in the business of writing rules here nor their
exceptions. I was just pointing you at the existing rules, and how this
seemed to violate them. Since the websites have moved around a bit since
the last time, here's the page I referenced:

https://wireless.docs.kernel.org/en/latest/en/developers/documentation/submittingpatches.html#new-driver

I suppose maybe those rules are there so that we don't get drivers with
*no* legally-usable firmware, since it's about "New Drivers". This is
not a New Driver, so maybe that part doesn't have to apply.

I suppose I'll leave it up to Johannes on this part, and may be willing
to retract my NAK [1].

Patch 3 is a different story. At the moment, it's definitely not
acceptable. But I tried to provide hints about how you can write proper
FW compatibility logic. I'm still not optimistic that'll be easy and
maintainable, and we still reserve the right to reject patches if they
make things unmaintainable.

(Marvell clearly didn't do any real work here on maintaining good FW
compatibility.)
