The following commit has been merged in the master branch: commit 82047ad7fecdc2d58bbeeb3872811b1c528fdf10 Author: Sven Eckelmann sven@narfation.org Date: Sun Jan 17 11:01:10 2016 +0100

batman-adv: Rename batadv_hardif *_free_ref function to *_put

The batman-adv source code is the only place in the kernel which uses the *_free_ref naming scheme for the *_put functions. Changing it to *_put makes it more consistent and makes it easier to understand the connection to the *_get functions.
