Subject: [PATCH 3695/4131] drm/amd/pp: fix "Delete the wrapper layer of
smu_allocate/free_memory"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
For amdgpu_bo_create_kernel to work the handle must be NULL initialized,
otherwise we only try to pin and map the BO.
