It looks as though this fails only for in-source builds, which is
something I usually don't test. I'm working on a patch to fix this.

Thanks,

This should be fixed in today's linux-next by:

commit 702800b5d6f45b18db6b6d6b1057af6fd1c75e20
Author: Thierry Reding <treding@nvidia.com>
Date:   Wed Aug 23 19:13:26 2017 +0200

    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.
