+1.
Andrew did ACK this via DRM here [1].
When we take external subsystem patches through DRM, our merge script
requires ACKs from an external maintainer, as determined by
get_maintainers.pl.
I’m not sure what happened here, but it looks like Andrew’s ACK was lost
on the patch, and somehow our merge tool allowed it to go in regardless.
We will be more diligent going forward.
Matt
