In addition to the qdev_create() patterns converted so far, we have a
qdev_set_parent_bus() pattern. Mostly when we embed a device in a
parent device rather than allocating it on the heap.
This pattern also puts devices in the dangerous "no QOM parent, but
plugged into bus" state I explained in recent commit "qdev: New
qdev_new(), qdev_realize(), etc."
Apply same solution: convert to qdev_realize(). Coccinelle script:
@@
expression dev, bus, errp;
symbol true;
@@
- qdev_set_parent_bus(DEVICE(dev), bus);
...
- object_property_set_bool(OBJECT(dev), true, "realized", errp);
+ qdev_realize(DEVICE(dev), bus, errp);
@ depends on !(file in "qdev-monitor.c") && !(file in "hw/core/qdev.c")@
expression dev, bus, errp;
symbol true;
@@
- qdev_set_parent_bus(dev, bus);
...
- object_property_set_bool(OBJECT(dev), true, "realized", errp);
+ qdev_realize(dev, bus, errp);
@@
expression dev, bus;
symbol true;
@@
- qdev_set_parent_bus(DEVICE(dev), bus);
...
- qdev_init_nofail(DEVICE(dev));
+ qdev_realize(DEVICE(dev), bus, &error_fatal);
Unconverted uses of qdev_set_parent_bus() remain. They'll be
converted later in this series.
