From: Thomas Huth <th...@redhat.com>
"make check-qtest-aarch64" recently started failing on FreeBSD builds,
and valgrind on Linux also detected that there is something fishy with
the new stm32l4x5-usart: The code forgot to set the correct class_size
here, so the various class_init functions in this file wrote beyond
the allocated buffer when setting the subc->type field.
