Steven Rostedt cad1d5bd2c tracing: Have event_enable_write() just return error on error ... The event_enable_write() function is inconsistent in how it returns errors. Sometimes it updates the ppos parameter and sometimes it doesn't. Simplify the code to just return an error or the count if there isn't an error.
