From my past knowledge of the arm64 defconfig, I think it's a bit of a
free-for-all, sort of like updates to the "MAINTAINERS" file. Doing a
"git log" on it I see commits happen from every corner and very few of
them have Acks. I think many (but not all) of the commits to this
file go through trees that feed into the SoC tree (Arnd and Olof)
because those maintainers care about enabling drivers for boards that
they're supporting, but changes come from elsewhere too.
Obviously an Ack wouldn't hurt, though. Since get_maintainer points
at Will and Catalin I wouldn't say no if one of them wanted to Ack
patch #2 in the series. ;-)

I'll hold tight at the moment to avoid fragmenting the discussion
while we figure out if we need an Ack on the defconfig. If that gets
resolved and you're ready to land, do it. Otherwise I'll spin out a
clean version once I think the Ack question is resolved.

I get ya and I'm the same way, but everyone has a different workflow
and I try to make allowances if I can...
