That's what I suggest, yes.

Yes, we will have N maintainers modifying drivers/genpd/Makefile, all
adding their single obj-y line. A quite trivial conflict to manage.

I already have a set of patches to these drivers in my tree for v6.6, in
their current location.

I'm afraid I am unable to see how we're going to handle the merge
conflict you're going to create in linux-next. Perhaps you're proposing
to just never publish Ulf's patches to linux-next?

By me merging the immutable patch 1 and the qcom-patch, the conflicts
would be minimal, and except for the genpd/Makefile entirely handled by
me.
