From f729dc70dafec281e524f51ae496a72ea4f8e319 Mon Sep 17 00:00:00 2001 From: Marek Lindner Date: Sun, 26 Jul 2015 04:37:15 +0800 Subject: [PATCH] batman-adv: move hardif refcount inc to batadv_neigh_node_new() The batadv_neigh_node cleanup function 'batadv_neigh_node_free_rcu()' takes care of reducing the hardif refcounter, hence it's only logical to assume the creating function of that same object 'batadv_neigh_node_new()' takes care of increasing the same refcounter.
