No, no that's wrong. That timeline_syncobj is NULL is not an error. In other words when args->vm_timeline_syncobj_out == 0 then amdgpu_gem_update_timeline_node() should just set timeline_syncobj=NULL and return 0. The error happens only if either args->vm_timeline_syncobj_out has a handler we can't find or if we fail to allocate memory for the timeline_chain. In this case the return value should be EINVAl or ENOMEM and then we absolutely should abort the operation.
Noted. Thank you, Arvind
