Masami Hiramatsu fixed another bug. This time returning a proper
result in event_enable_func(). After checking the return status of try_module_get(), it returned the status of try_module_get(). But try_module_get() returns 0 on failure, which is success for event_enable_func(). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQEcBAABAgAGBQJRnQn/AAoJEOdOSU1xswtMVDUH/3rOPX2/sbc817NN+KjXJiQi 1O8tmiOcaqMh742Df2YWSqXeM5IjARjl/xSZqazpGaDVu6HnMbEeb3Frx9hpzOPu VEtBapasrPK6TOYSDfLaUuRsxuzSEsXR4dUexSh3o7f0/b1dY8x0BwiYxz3tz5BS x6HX9OptUXUKDrloNC0qlX7ymuWmaeGULsTgCYYORfMe2FRFfvJhoCZFgC6dLw5x YTubQuhVyNOD/X5jXM5h9kkUSw70VjGMhlqilyp0YLcnrhFL/QhCi7WR3b3hDwcp MUpJyMAaPXlQHs2Q/gh46XldyhULPXamrujx8ISsDDdMQlWsWPTsQgfJ8e4/zsQ= =n9S7 -----END PGP SIGNATURE----- Merge tag 'trace-fixes-v3.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fix from Steven Rostedt: "Masami Hiramatsu fixed another bug.
