It is useful to test the\nerror handling of notifier call chain failures.\n\nThis adds common basic functions to define which type of events can be\nfail and to initialize the debugfs interface to control what error code\nshould be returned and which event should be failed.\n\nSigned-off-by: Akinobu Mita \u003cakinobu.mita@gmail.com\u003e\nCc: Pavel Machek \u003cpavel@ucw.cz\u003e\nCc: \"Rafael J.
