Hi all,

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

drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c: In function 'amdgpu_amdkfd_gpuvm_free_memory_of_gpu':
drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c:1357:2: error: implicit declaration of function 'drm_gem_object_put_unlocked'; did you mean 'drm_gem_object_put_locked'? [-Werror=implicit-function-declaration]
 1357 |  drm_gem_object_put_unlocked(&mem->bo->tbo.base);
      |  ^~~~~~~~~~~~~~~~~~~~~~~~~~~
      |  drm_gem_object_put_locked

Caused by commit

  ab15d56e27be ("drm: remove transient drm_gem_object_put_unlocked()")

interacting with commit

  fd9a9f8801de ("drm/amdgpu: Use GEM obj reference for KFD BOs")

from Linus' tree.

I have applied the following merge fix up patch for today.
