Subject: [PATCH] hw/virtio/virtio-mem: Fix definition of VirtIOMEMClass
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Parent of VirtIOMEMClass is VirtioDeviceClass rather than VirtIODevice.
This isn't catastrophic only because sizeof(VirtIODevice) >
sizeof(VirtioDeviceClass).

Fixes: 910b25766b33 ("virtio-mem: Paravirtualized memory hot(un)plug")
