please let me ask you to swap your and Thara's sob tags above, there is
a rule applicable to all cases dealing with someone's else changes:

 From Documentation/process/submitting-patches.rst:

   Any further SoBs (Signed-off-by:'s) following the author's SoB are from
   people handling and transporting the patch, but were not involved in its
   development. SoB chains should reflect the **real** route a patch took
   as it was propagated to the maintainers and ultimately to Linus, with
   the first SoB entry signalling primary authorship of a single author.
