Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in:

drivers/gpu/drm/i915/display/intel_plane.c

between commit:

bfa71b7a9dc6b ("drm/i915: Unlink NV12 planes earlier")

from the drm-intel-fixes tree and commits:

017ecd0498557 ("drm/i915: Unlink NV12 planes earlier")
7b3a14322d1a8 ("drm/i915: Relocate unlink_nv12_plane()")
c5121204ad991 ("drm/i915: Skip redundant NV12 plane unlinking")

from the drm-intel tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
