drm/amdgpu: rework synchronization of VM updates v4
If provided we only sync to the BOs reservation object and no longer to the root PD. v2: update comment, cleanup amdgpu_bo_sync_wait_resv v3: use correct reservation object while clearing v4: fix typo in amdgpu_bo_sync_wait_resv Signed-off-by: Christian König <christian.koenig@amd.com> Tested-by: Tom St Denis <tom.stdenis@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
