Once more a maintainer who acks a patch and doesn't push it. This is
really confusing, who exactly do you expect to handle this patch for you?

Please push to drm-misc-next (also for future patches), thanks.

Hi Daniel
I Saw the patch title is "[PATCH 7/7]", I guessed it's one of a series of patches and maybe it can pushed by series.

Ok, Pushed it to drm-misc-next.

Hm right, but I only see 7/7 here. Either way, except when the author asks
for a preferred tree it's best if you just pick things up right away. And
if you're unsure, just ask instead of risking that a patch drops through
the cracks.
