STRUCT CCW_DEVICE(9)                       The ccw bus                       STRUCT CCW_DEVICE(9)



NAME
       struct_ccw_device - channel attached device

SYNOPSIS
       struct ccw_device {
         spinlock_t * ccwlock;
         struct ccw_device_id id;
         struct ccw_driver * drv;
         struct device dev;
         int online;
         void (* handler) (struct ccw_device *, unsigned long, struct irb *);
       };

MEMBERS
       ccwlock
           pointer to device lock

       id
           id of this device

       drv
           ccw driver for this device

       dev
           embedded device structure

       online
           online status of device

       handler
           interrupt handler

DESCRIPTION
       handler is a member of the device rather than the driver since a driver can have different
       interrupt handlers for different ccw devices (multi-subchannel drivers).
