      I think the problem comes from "markers: fix duplicate modpost entry"
      (commit d35cb360
      Especially :
        -   add_marker(mod, marker, fmt);
        +   if (!mod->skip)
        +     add_marker(mod, marker, fmt);
      Here is a fix that should take care if this problem.
      Thanks for the bug report!
