qom/object.c provides object_property_get_TYPE() and object_property_set_TYPE() for a number of common types. These are all convenience wrappers around object_property_get_qobject() and object_property_set_qobject(). Except for object_property_get_uint16List(), which is unusual in two ways: * It bypasses object_property_get_qobject(). Fixable; the previous commit did it for object_property_get_enum()) * It stores the value through a parameter. Its contract claims it returns the value, like the other functions do. Also fixable. Fixing is not worthwhile, though: object_property_get_uint16List() has seen exactly one user in six years. Convert the lone user to do its job with the generic object_property_get_qobject(), and drop object_property_get_uint16List().
