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

Hi all,

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

  drivers/gpu/drm/amd/amdgpu/amdgpu_device.c

between commits:

  9adb125dde69 ("drm/amdgpu: re-enable suspend phase 2 for S0ix")
  4021229e32bd ("drm/amdgpu/swsmu: skip gfx cgpg on s0ix suspend")
  9bb735abcbd8 ("drm/amdgpu: update comments about s0ix suspend/resume")

from Linus' tree and commit:

  e3c1b0712fdb ("drm/amdgpu: Reset the devices in the XGMI hive duirng probe")

from the drm 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.
