From: Thierry Reding <treding@xxxxxxxxxx>
The header comment in include/trace/define_trace.h specifies that the
TRACE_INCLUDE_PATH needs to be relative to the define_trace.h header
rather than the trace file including it. Most instances get that wrong
and work around it by adding the $(src) directory to the include path.
While this works, it is preferable to refer to the correct path to the
trace file in the first place and avoid any workaround.

Actually I've recently wondered how to correctly do this since we send
out a TTM patch for 4.13 which most likely gets this wrong as well.
Thanks for pointing this out, patch #2 and #5 are Reviewed-by: Christian
König <christian.koenig@xxxxxxx>
The rest is Acked-by: Christian König <christian.koenig@xxxxxxx>.
Tom please check our TTM patch and if necessary provide a fix as well.
Thanks,
Christian.
