Steven Rostedt (Google) 70a6ed553f tracing: Use EVENT_NULL_STR macro instead of open coding "(null)"
The TRACE_EVENT macros has some dependency if a __string() field is NULL,
where it will save "(null)" as the string. This string is also used by
__assign_str(). It's better to create a single macro instead of having
something that will not be caught by the compiler if there is an
unfortunate typo.
