In fact that's a false statement, because first thing these functions do is drop the cast to const with container_of: struct scmi_info *info = handle_to_scmi_info(handle); And with such cast the handle is easily writable with simple: info->handle.dev = NULL; If the function really was not modifying the pointed handle, it would use the container_of_const() call. The code is not correct logically, either, because functions like scmi_notification_instance_data_set() are meant to modify the data behind the handle (in containing struct).
