[PATCH] ftrace: fix check for return value of register_module_notifier in event_trace_init

From: Ming Lei
Date: Mon May 18 2009 - 11:04:46 EST


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]
