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

Hi all,

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

  drivers/gpu/drm/imx/ipuv3-plane.c

between commits:

  ba5c1649465d ("drm: Rename plane atomic_check state names")
  41016fe1028e ("drm: Rename plane->state variables in atomic update and disable")

from the drm tree and commit:

  49c826e1941a ("drm/imx: Add 8 pixel alignment fix")

from the imx-drm 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.
