For the maintainers, yes.  But it avoids setting up k.o accounts and git
repos for each device driver maintainer that has this issue.

Yes, and that would still be the case, from my understanding:  Instead of
each driver having a k.o. signed git repo, we ask the maintainers to stage
this common branch that both maintainers pull from into their -next
branches/repos.

I meant using rc-1 for the current release when submitting these shared
commits for the _following merge window_.
