One that's a bit more powerful than the recent patch
proposal, I'd say, since it chains.

Most do.  In fact, that one *does* ... what's your point?

If I hadn't know that more generic threaded IRQ support
was already on the way, I might have done more with that
particular driver than just massive cleanup.  I stopped
short of some changes that it seemed genirq should obviate
before too long.  As always, more cleanup *could* be done.
