Hi all,

After merging the drm-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_module.c:25:

Caused by commit

  4e98f871bcff ("drm: delete drmP.h + drm_os_linux.h")

interacting with commit

  6b855f7b83d2 ("drm/amdkfd: Check against device cgroup")

from the amdgpu tree.

I added the following merge fix patch for today:
