Actually, cu_mask has been copied to mqd memory and does't have to persist in queue_properties. Remove it from queue_properties. And use struct mqd_update_info to store such properties, then pass it to update queue operation. v2: * Rename pqm_update_queue to pqm_update_queue_properties. * Rename struct queue_update_info to struct mqd_update_info. * Rename pqm_set_cu_mask to pqm_update_mqd.
