Antonio Quartulli says:

====================
pull request [net-next]: batman-adv 20160223

This is a cleanup patchset: first the BATADV_BONDING_TQ_THRESHOLD
constant gets removed as it was defined but not used anywhere,
then all our *_free_ref functions are renamed to *_put in order
to follow the kernel naming convention by Sven Eckelmann.
