Ok, I lie...

    bus_info = visorbus_get_device_by_id(bus_no, BUS_ROOT_DEVICE, NULL);
    if (!bus_info) {
        POSTCODE_LINUX_3(BUS_CONFIGURE_FAILURE_PC, bus_no,
                 POSTCODE_SEVERITY_ERR);
        rc = -CONTROLVM_RESP_ERROR_BUS_INVALID;
    } else if (bus_info->state.created == 0) {
        POSTCODE_LINUX_3(BUS_CONFIGURE_FAILURE_PC, bus_no,
                 POSTCODE_SEVERITY_ERR);
        rc = -CONTROLVM_RESP_ERROR_BUS_INVALID;
    } else if (bus_info->pending_msg_hdr) {
        POSTCODE_LINUX_3(BUS_CONFIGURE_FAILURE_PC, bus_no,
                 POSTCODE_SEVERITY_ERR);
        rc = -CONTROLVM_RESP_ERROR_MESSAGE_ID_INVALID_FOR_CLIENT;
