From b236512280fb96dcca45a3f5bbae1839bd673e58 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 29 May 2015 09:48:13 -0300 Subject: perf kmem: Fix compiler warning about may be accessing uninitialized variable The last argument to strtok_r doesn't need to be initialized, its just a placeholder to make this routine reentrant, but gcc doesn't know about that and complains, breaking the build, fix it by setting it to NULL.
