From d7d6de9530db7e385a05e1ae6cde642a617e6c89 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Sat, 5 Mar 2016 16:09:18 +0100 Subject: [PATCH] batman-adv: Increase hard_iface refcnt for ptype The hard_iface is referenced in the packet_type for batman-adv. Increase the refcounter of the hard_interface for it to have an explicit reference for it in case this functionality gets refactorted and the currently used implicit reference for it will be removed.
