Code which creates a kobject must, of course, initialize that object. Some
of the internal fields are setup with a (mandatory) call to kobject_init()::
- void kobject_init(struct kobject *kobj, struct kobj_type *ktype);
+ void kobject_init(struct kobject *kobj, const struct kobj_type *ktype);
The ktype is required for a kobject to be created properly, as every kobject
must have an associated kobj_type. After calling kobject_init(), to
