ftrace: fix check for return value of register_module_notifier in event_trace_init
register_module_notifier() returns zero in the success case. So fix the inverted fail case check in trace events modules handler. [ Impact: fix spurious warning on ftrace initialization] Reported-by: Li Zefan <lizf@cn.fujitsu.com> Signed-off-by: Ming Lei <tom.leiming@gmail.com> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
