3.16.7-ckt13 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Steven Rostedt <[email protected]> commit 37815bf866ab6722a47550f8d25ad3f1a16a680c upstream. The module notifier call chain for MODULE_STATE_COMING was moved up before the parsing of args, into the complete_formation() call. But if the module failed to load after that, the notifier call chain for MODULE_STATE_GOING was never called and that prevented the users of those call chains from cleaning up anything that was allocated.
