The event_filter_write() function calls event_file_file() to retrieve a trace_event_file associated with a given file struct. If a non-NULL pointer is returned, the function then checks whether the trace_event_file instance has the EVENT_FILE_FL_FREED flag set. This check is redundant because event_file_file() already performs this validation and returns NULL if the flag is set. The err value is also already initialized to -ENODEV. Remove the unnecessary check for EVENT_FILE_FL_FREED in event_filter_write().
