This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read Documentation/stable_kernel_rules.txt
for how to do this properly.

Not sure what exactly your script latched onto, but at least in the drm
subsystem it's pretty common to remind maintainers with a reply just
containing

Cc: stable@vger.kernel.org

that they need to add that to the patch when applying. Often combined with
an r-b/a-b tag. And Damien is working to teach patchwork to auto-add
those, so yeah it's indeed the right way to submit a patch for stable. At
least here ;-)

Cheers, Daniel
