      Failure scenarios for driver and device need to be documented:

      • driver must check for failures of WRITE_STATUS and treat device as unusable
      • device must post failure of WRITE_STATUS if the driver tries to set a wrong state

      The WRITE_STATUS ccw command needs to be able to fail, e.g. when the driver wants to set FEATURES_OK but the device can't work with the features.
