linux-next: manual merge of the drm tree with the drm-fixes tree

[Mark Brown <broonie@kernel.org>]

Hi all,

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

  drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm_crtc.c

between commits:

  8382cd234981a ("drm/amd/display: consolidate DCN vblank/flip handling onto vupdate_no_lock")
  82730dba0cf9d ("drm/amd/display: Fix flip-done timeouts on mode1 reset")

from the drm-fixes tree and commit:

  c87e6635d2db0 ("drm/amd/display: consolidate DCN vblank/flip handling onto vupdate_no_lock")

from the 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.
