// For simplicity we assume some things about the code we're modifying
|
|
// that happen to be true for all our targets:
|
|
// * all cpu_class_set_parent_reset() callsites have a 'DeviceClass *dc' local
|
|
// * the parent reset field in the target CPU class is 'parent_reset'
|
|
// * no reset function already has a 'dev' local
