ops, I created the confusion. Sorry.
What I decided that week was to not pull to drm-intel-fixes until Ville
or Jani acking. But it was already part of dinq, so moving to drm-next
and I didn't removed or reverted it.
So... But ville acked on irc and I pulled to -fixes on the following week
as well.
So yes, patch is there ;)
