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/display/intel_display.c

between commit:

  1b321026e213 ("drm/i915: Pass ww ctx to intel_pin_to_display_plane")

from the drm tree and commit:

  61169987c4d9 ("drm/i915: Unify the FB and plane state view information into one struct")

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.

Cheers,
Stephen Rothwell
