[Qemu-devel] [PATCH RFC 04/11] s390x/virtio-ccw: fix check for WRITE_FEAT

[Cornelia Huck <cornelia.huck@de.ibm.com>]

We need to check guest feature size, not host feature size to find
out whether we should call virtio_set_features(). This check is
possible now that vdev->guest_features is an array.
