 /**
  * class_create - create a struct class structure
  * @owner: pointer to the module that is to "own" this struct class
  * @name: pointer to a string for the name of this class.
  * @key: the lock_class_key for this class; used by mutex lock debugging
  *
  * 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().
