while (++i < dw->sd_count) {
               if (!strcmp(dw->sd[i].bus_id, param)) {
       chan->private = &dw->sd[i];
       last_dw = NULL;
       last_bus_id = NULL;

       return true;
               }
       }

               last_dw = dw;
               last_bus_id = param;
               return false;
