Greg Kroah-Hartman ddaf098ea7 driver core: class: properly reference count class_dev_iter() ... When class_dev_iter is initialized, the reference count for the subsys private structure is incremented, but never decremented, causing a memory leak over time. To resolve this, save off a pointer to the internal structure into the class_dev_iter structure and then when the iterator is finished, drop the reference count.
