- * hci_conn_get() and hci_conn_put() are used to control the life-time of an

- * and can be dereferenced. So you can use its locks, local variables and any
- * other constant data.
- * Before accessing runtime data, you _must_ lock the object and then check that
- * it is still running. As soon as you release the locks, the connection might
- * get dropped, though.
- *
- * On the other hand, hci_conn_hold() and hci_conn_drop() are used to control
- * how long the underlying connection is held. So every channel that runs on the
- * hci_conn object calls this to prevent the connection from disappearing. As
- * long as you hold a device, you must also guarantee that you have a valid
- * reference to the device via hci_conn_get() (or the initial reference from
- * hci_conn_add()).
- * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't
- * break because nobody cares for that. But this means, we cannot use
- * _get()/_drop() in it, but require the caller to have a valid ref (FIXME).
