Every tracing file must have its own TRACE_SYSTEM defined.
The brcmsmac tracepoint header broke this and added in the middle
of the file:

 #undef TRACE_SYSTEM
 #define TRACE_SYSTEM brcmsmac

 #undef TRACE_SYSTEM
 #define TRACE_SYSTEM brcmsmac_tx

 #undef TRACE_SYSTEM
 #define TRACE_SYSTEM brcmsmac_msg

Unfortunately, this broke new code in the ftrace infrastructure.
Moving each of these TRACE_SYSTEMs into their own trace file with
just one TRACE_SYSTEM per file fixes the issue.
