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).
