		struct ccwgroup_driver *	gdrv,
		int	num_devices,
		const char *	buf
	)

ccwgroup_create_dev() - create and register a ccw group device : parent device for the new device : driver for the new group device : number of slave devices : buffer containing comma separated bus ids of slave devices

Create and register a new ccw group device as a child of . Slave devices are obtained from the list of bus ids given in . Returns: %0 on success and an error code on failure. Context: non-atomic

void ccwgroup_driver_unregister

(

struct ccwgroup_driver *

cdriver

)

ccwgroup_driver_unregister() - deregister a ccw group driver : driver to be deregistered

This function is mainly a wrapper around driver_unregister().

int ccwgroup_probe_ccwdev

(

struct ccw_device *

cdev

)

ccwgroup_probe_ccwdev() - probe function for slave devices : ccw device to be probed

This is a dummy probe function for ccw devices that are slave devices in a ccw group device. Returns: always %0

Definition at line 581 of file ccwgroup.c.

void ccwgroup_remove_ccwdev

(

struct ccw_device *

cdev

)

ccwgroup_remove_ccwdev() - remove function for slave devices : ccw device to be removed

This is a remove function for ccw devices that are slave devices in a ccw group device. It sets the ccw device offline and also deregisters the embedding ccw group device.
