qom: Less verbose object_initialize_child() All users of object_initialize_child() pass the obvious child size argument. Almost all pass &error_abort and no properties. Tiresome. Rename object_initialize_child() to object_initialize_child_with_props() to free the name. New convenience wrapper object_initialize_child() automates the size argument, and passes &error_abort and no properties. Rename object_initialize_childv() to object_initialize_child_with_propsv() for consistency. Convert callers with this Coccinelle script: @@ expression parent, propname, type; expression child, size; symbol error_abort; @@ - object_initialize_child(parent, propname, OBJECT(child), size, type, &error_abort, NULL) + object_initialize_child(parent, propname, child, size, type, &error_abort, NULL) @@ expression parent, propname, type; expression child; symbol error_abort; @@ - object_initialize_child(parent, propname, child, sizeof(*child), type, &error_abort, NULL) + object_initialize_child(parent, propname, child, type) @@ expression parent, propname, type; expression child; symbol error_abort; @@ - object_initialize_child(parent, propname, &child, sizeof(child), type, &error_abort, NULL) + object_initialize_child(parent, propname, &child, type) @@ expression parent, propname, type; expression child, size, err; expression list props; @@ - object_initialize_child(parent, propname, child, size, type, err, props) + object_initialize_child_with_props(parent, propname, child, size, type, err, props) 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.
