linux-next: manual merge of the amdgpu tree with the drm-misc tree

[Stephen Rothwell]

Hi all,

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

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

between commits:

  537ef0f88897 ("drm/amd/display: use new vblank enable policy for DCN35+")
  e45b6716de4b ("drm/amd/display: use a more lax vblank enable policy for DCN35+")
  58a261bfc967 ("drm/amd/display: use a more lax vblank enable policy for older ASICs")

from the drm-misc tree and commit:

  7fb363c57522 ("drm/amd/display: Let drm_crtc_vblank_on/off manage interrupts")

from the amdgpu tree.

I fixed it up (I think - 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.
