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/pm/swsmu/amdgpu_smu.c

between commit:

  b19515253623 ("drm/amd/pm: setup APU dpm clock table in SMU HW initialization")

from the Linus tree and commits:

  82cac71c1b64 ("drm/amd/pm: put Navi1X umc cdr workaround in post_smu_init")
  236b156f7388 ("drm/amd/pm: apply no power source workaround if dc reported by gpio")
  1653a179c822 ("drm/amd/pm: move NAVI1X power mode switching workaround to post_init")

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.
