Actually, there's no interface change. This is the work-around patch to
that. It's only internal to the kernel and userspace does not see any
difference.

I just needed a unique TRACE_SYSTEM name that was also a valid C
variable, and now use TRACE_SYSTEM_VAR.

The ftrace code now has:

#ifndef TRACE_SYSTEM_VAR
#define TRACE_SYSTEM_VAR TRACE_SYSTEM
#endif

And this allows trace headers (like intel-sst.h) to have a different
VAR variable from the TRACE_SYSTEM name:

#define TRACE_SYSTEM intel-ssl

#define TRACE_SYSTEM_VAR intel_ssl

This lets me use something that will work and not need to change what
the user space sees.

Sorry, I got that from git log include/trace/events/intel-sst.h

I couldn't find anything in MAINTAINERS about that file, but I didn't
look for your name though.
