924 * hci_conn_get() and hci_conn_put() are used to control the life-time of an
925 * "hci_conn" object. They do not guarantee that the hci_conn object is running,
926 * working or anything else. They just guarantee that the object is available
927 * and can be dereferenced. So you can use its locks, local variables and any
928 * other constant data.
929 * Before accessing runtime data, you _must_ lock the object and then check that
930 * it is still running. As soon as you release the locks, the connection might
931 * get dropped, though.
933 * On the other hand, hci_conn_hold() and hci_conn_drop() are used to control
934 * how long the underlying connection is held. So every channel that runs on the
935 * hci_conn object calls this to prevent the connection from disappearing. As
936 * long as you hold a device, you must also guarantee that you have a valid
937 * reference to the device via hci_conn_get() (or the initial reference from
939 * The hold()/drop() ref-count is known to drop below 0 sometimes, which doesn't
940 * break because nobody cares for that. But this means, we cannot use
941 * _get()/_drop() in it, but require the caller to have a valid ref (FIXME).
