Caused by commit

  806cb2270237 ("kunit: Annotate _MSG assertion variants with gnu printf specifiers")

interacting with commit

  c70703320e55 ("drm/tests/drm_buddy: add alloc_range_bias test")

I have applied the following patch for today (this should probably
actually be fixed in the drm-misc-fixes tree).
