Hi all,

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

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

between commit:

  67cf83ac8316a ("Revert "drm/sched: Embed run queue singleton into the scheduler"")

from the drm-misc-fixes tree and commits:

  4a33d82e224c8 ("drm/amdgpu: protect XCP scheduler selection")
  fa1531170d2c9 ("drm/amdgpu: add check for xcp id")
  6e8a3c24bd75f ("drm/amdgpu: bounds check xcp_id in release_sched")
  7445035dd3f22 ("drm/amdgpu: bounds check xcp ip block index")
  62d8b452615fd ("drm/amdgpu: Fix kobject cleanup in xcp sysfs")

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.
