3.13-stable review patch. If anyone has any objections, please let me know. ------------------ From: Antonio Quartulli <antonio@xxxxxxxxxxxxxx> [ Upstream commit a5a5cb8cab526af2f6cbe9715f8ca843192f0d81 ] In the failure path of the orig_node initialization routine the orig_node->bat_iv.bcast_own field is free'd twice: first in batadv_iv_ogm_orig_get() and then later in batadv_orig_node_free_rcu(). Fix it by removing the kfree in batadv_iv_ogm_orig_get().
