I missed this revision before sending my last mail.
I tried to apply this patch but every patch confliced due to other
changes since the kernel this is based on.

I need you to generate a new patch on top of drm-misc-next,
or as an alternative on top of linux-next.
You are in a much better position to do this right than I am.

Sorry for the troubles!

No worries! Just sent a v6 rebased on linux-next.

I am never sure if my patches should be based on master or linux-next.
Sorry for the conflicts.
