struct class * __class_create(struct module * owner, const char * name, struct lock_class_key * key);

owner

This is used to create a struct class pointer that can then be used in calls to device_create.

Returns struct class pointer on success, or ERR_PTR on error.

Note, the pointer created here is to be destroyed when finished by making a call to class_destroy.
