All remaining conversions to qdev_realize() are for bus-less devices. Coccinelle script: // only correct for bus-less @dev! @@ expression errp; expression dev; @@ - qdev_init_nofail(dev); + qdev_realize(dev, NULL, &error_fatal); @ depends on !(file in "hw/core/qdev.c") && !(file in "hw/core/bus.c")@ expression errp; expression dev; symbol true; @@ - object_property_set_bool(OBJECT(dev), true, "realized", errp); + qdev_realize(DEVICE(dev), NULL, errp); @ depends on !(file in "hw/core/qdev.c") && !(file in "hw/core/bus.c")@ expression errp; expression dev; symbol true; @@ - object_property_set_bool(dev, true, "realized", errp); + qdev_realize(DEVICE(dev), NULL, errp); Note that Coccinelle chokes on ARMSSE typedef vs. macro in hw/arm/armsse.c. Worked around by temporarily renaming the macro for the spatch run.
