[Qemu-devel] [PATCH 28/61] virtio-scsi-s390 : switch to the new API.

[fred . konrad]

From: KONRAD Frederic <fred.kon...@greensocs.com>

Here the virtio-scsi-s390 is modified for the new API. The device
virtio-scsi-s390 extends virtio-s390-device as before. It creates and
connects a virtio-scsi during the init. The properties are not modified.
