Commit Message

Peter Maydell Feb. 16, 2018, 1:45 p.m. UTC 
Use the new sysbus_init_child() function rather than
opencoding the init-and-parent operations.

This commit was created with coccinelle:
spatch --in-place -sp_file sysbus-init-child.spatch --keep-comments hw/arm/bcm2835_peripherals.c

and the following spatch file:
@@
expression CHILD, CHILDTYPE, POBJ, CHILDNAME, ERREXPR;
@@
- object_initialize(&CHILD, sizeof(CHILD), CHILDTYPE);
- object_property_add_child(POBJ, CHILDNAME, OBJECT(&CHILD), ERREXPR);
- qdev_set_parent_bus(DEVICE(&CHILD), sysbus_get_default());
+ sysbus_init_child(POBJ, CHILDNAME, &CHILD, sizeof(CHILD), CHILDTYPE);
