So now there are two contesting patches for this and that creates a
social problem for us as maintainers. I am not too happy about that.

This situation activates the kernel management style document so
I advise involved parties to familiarize themselves with it:
https://www.kernel.org/doc/html/latest/process/management-style.html

Can we get the discussion down to actual technical points?
We really need a virtio GPIO driver, no doubt, so if everyone could
just work toward that goal and compromise with their specific pet
peeves that would be great.

Yours,
