From c1bacea053fdaa20cbb37287eb33198ddef255bd Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Wed, 22 Feb 2017 17:16:39 +0100 Subject: batman-adv: Reduce preprocessor checks in multicast.c It is not necessary to disable these code sections in case other kernel features are disabled. Instead the IS_ENABLED tests can be added directly in the code and the compiler can remove the unnecessary code parts during its optimization run.
