[PATCH 0/2] virtio-ccw: new status accessor in device
These patches implement the new read status command in qemu and bump
the revision to 2 (as this ccw is currently the only thing new with
that revision); see "[PATCH v2 1/1] ccw: add CCW_CMD_READ_STATUS"
for details.
Note that we'll need to add some compat machine handling when this
is added (not done here, as the machine level is not clear yet).
Changes from the RFC (back in September):
- removed stray ';' in patch 1
- rebased
