[Intel-gfx] linux-next: manual merge of the drm-intel tree with the drm tree

[Stephen Rothwell]

Hi all,

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

  drivers/gpu/drm/i915/i915_drv.h

between commit:

  f67986b0119c ("drm/i915/pxp: Promote pxp subsystem to top-level of i915")

from the drm tree and commit:

  a3f839762ceb ("drm/i915: move pch_ssc_use to display sub-struct under dpll")

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.

Stephen Rothwell
