Subject[PATCH 04/14] perf kmem: Fix compiler warning about may be accessing uninitialized variable
Date
From: Arnaldo Carvalho de Melo <acme@redhat.com>

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.
