The following change to commit 607638faf2ff ("s390/qdio: handle deferred cc1") fixes the compile error on v5.15: --- a/drivers/s390/cio/qdio_main.c +++ b/drivers/s390/cio/qdio_main.c @@ -758,7 +758,7 @@ void qdio_int_handler(struct ccw_device *cdev, unsigned long intparm, if (rc == -EAGAIN) { DBF_DEV_EVENT(DBF_INFO, irq_ptr, "qint retry"); - rc = ccw_device_start(cdev, irq_ptr->ccw, intparm, 0, 0); + rc = ccw_device_start(cdev, &irq_ptr->ccw, intparm, 0, 0); if (!rc) return; DBF_ERROR("%4x RETRY ERR", irq_ptr->schid.sch_no);
