Is there an easy way to backport this to 4.19 mainline? Would be very useful to integrate the fix into stable kernels.

As it is currently it wont work on 4.19 because it uses <drm/drm_atomic_uapi.h> which isnt mainlined yet. Brandon's hack works on 4.19 just in case it matters.

Just remove the header include. There was some refactoring, and the functions needed in that file are in the others included.

Last question, is this patch https://patchwork.freedesktop.org/patch/263412/ you just submitted related to this issue?

Looks like it's related. Thanks for taking on our issue, Nicholas.
