I may have misunderstood how cleanup works, but this is what I thought: The cleanup is defined in of.h as: DEFINE_FREE(device_node, struct device_node *, if (_T) of_node_put(_T)) Doesn't this mean that it handles the case where `child` is NULL, by not calling of_node_put() ? So it should either be a valid constructor or NULL and not some stale value. > You probably wanted scoped loop below. Ahh, didn't realize we have that available. -- viresh
