    Subject[patch/s390 26/46] cio: Use ccw_device_set_notoper().
    From: Cornelia Huck <cornelia.huck@de.ibm.com>

    Use ccw_device_set_notoper() (which also deletes the device
    timer and disables the subchannel) instead of simply setting
    the state to DEV_STATE_NOT_OPER in the generic not operational
    handling code. This prevents unexpected interrupts popping up
    for devices that are deemed not operational.
