Check the stream pointer passed to string_stream_destroy() for IS_ERR_OR_NULL() instead of only NULL. Whatever alloc_string_stream() returns should be safe to pass to string_stream_destroy(), and that will be an ERR_PTR. It's obviously good practise and generally helpful to also check for NULL pointers so that client cleanup code can call string_stream_destroy() unconditionally - which could include pointers that have never been set to anything and so are NULL.
