From 9bb218828c8f4fa6587af93e248903c96ce469d0 Mon Sep 17 00:00:00 2001 From: Markus Pargmann Date: Fri, 26 Dec 2014 12:41:18 +0100 Subject: batman-adv: debugfs, avoid compiling for !DEBUG_FS Normally the debugfs framework will return error pointer with -ENODEV for function calls when DEBUG_FS is not set. batman does not notice this error code and continues trying to create debugfs files and executes more code. We can avoid this code execution by disabling compiling debugfs.c when DEBUG_FS is not set.
