tracing/events: Only define remove_subsystem_dir() if CONFIG_MODULES
If we disable modules, we get the following warning in ftrace events file: kernel/trace/trace_events.c:912: attention : ‘remove_subsystem_dir’ defined but not used remove_subystem_dir() is useless if !CONFIG_MODULES, then move it to the appropriate #ifdef section of trace_events.c Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org>
