From 15d5ffdea0ddfa78609b1587851b13d9137fbbcd Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Fri, 15 Jul 2016 17:39:23 +0200 Subject: batman-adv: Place kref_get for tt_common near use It is hard to understand why the refcnt is increased when it isn't done near the actual place the new reference is used. So using kref_get right before the place which requires the reference and in the same function helps to avoid accidental problems caused by incorrect reference counting.
