Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in
drivers/gpu/drm/i915/intel_display.c between commit 62e537f8d568
("drm/i915: Fix frontbuffer false positve") from the drm-intel-fixes
tree and commit 6a418fcd84d6 ("drm/i915: Use fb modifiers in
intel_check_cursor_plane") from the drm-intel tree.

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