Dmitry had also reported this earlier and I think the right fix is this,
which is now in today's linux-next:

commit 702800b5d6f45b18db6b6d6b1057af6fd1c75e20

    drm/tegra: trace: Fix path to include

    The TRACE_INCLUDE_FILE macro needs to specify the path relative to the
    define_trace.h header rather than relative to the file defining it.
