Subject: linux-next: manual merge of the drm-intel tree with the drm tree

Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in
drivers/gpu/drm/i915/intel_dp.c between commit b19729617929 ("drm/i915:
fix psr match conditions screw ups") from the drm tree and commit
24acaf94ed4a ("drm/i915: Fix up PSR frontbuffer tracking") from the
drm-intel tree.

I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).
