Driver core: clean up removed functions from the documentation

struct kobject {

	const char		* k_name;

	char			name[KOBJ_NAME_LEN];

	struct kref		kref;

	struct list_head	entry;

	struct kobject		* parent;

is equivalent to doing:

struct kset devices_subsys = {

     .kobj = {

	   .name = "devices",

     },

     .ktype = &ktype_devices,

     .uevent_ops = &device_uevent_ops,

};

kobject_set_name(&devices_subsys, name);

The objects that are registered with a subsystem that use the

subsystem's default list must have their kset ptr set properly. These

objects may have embedded kobjects or ksets. The

following helpers make setting the kset easier:

following helper makes setting the kset easier:

kobj_set_kset_s(obj,subsys)

- Assumes that obj->kobj exists, and is a struct kobject.

- Sets the kset of that kobject to the kset <subsys>.

kset_set_kset_s(obj,subsys)

- Assumes that obj->kset exists, and is a struct kset.

- Sets the kset of the embedded kobject to the kset <subsys>.

subsys_set_kset(obj,subsys)

- Assumes obj->subsys exists, and is a struct subsystem.

- Sets obj->subsys.kset.kobj.kset to the subsystem's embedded kset.

void subsystem_init(struct kset *s);

int subsystem_register(struct kset *s);

void subsystem_unregister(struct kset *s);

struct kset *subsys_get(struct kset *s);

void kset_put(struct kset *s);

These are just wrappers around the respective kset_* functions.
