[qemu-s390x] [PATCH 0/2] s390x: reset handling for ccw devices

[Cornelia Huck]

On Friday, Thomas noticed some problems with 3270 devices. One result
was "s390x/css: disabled subchannels cannot be status pending", but
a reboot did not cure the previous broken status. Turns out that 3270
devices are missing a reset handler.

This series cleans up reset handling a bit and makes sure that the base
ccw device class provides a subchannel reset handler. I'm currently
not sure what we should do with vfio-ccw, so the behaviour there is
left unchanged.

  virtio-ccw: common reset handler
  s390x/ccw: make sure all ccw devices are properly reset
