Markus Armbruster e1c8237df5 qom: Fix invalid error check in property_get_str() ... When a function returns a null pointer on error and only on error, you can do if (!foo(foos, errp)) { ... handle error ... } instead of the more cumbersome Error *err = NULL; if (!foo(foos, &err)) { error_propagate(errp, err); ... handle error ... } A StringProperty's getter, however, may return null on success! We then fail to call visit_type_str(). Screwed up in 6a146eb, v1.1. Fails tests/qom-test in my current, heavily hacked QAPI branch. No reproducer for master known (but I didn't look hard).
