FYI, You don't add "Reported-by" and "Closes" tags for kernel test robot
reports for previous versions of a patch set.

It even says that in the report:

   If you fix the issue in a separate patch/commit (i.e. not just a new version of
   the same patch/commit), kindly add following tags
   | Reported-by: kernel test robot <lkp@intel.com>
   | Closes: https://lore.kernel.org/oe-kbuild-all/202503112205.joXgt8gR-lkp@intel.com/

"not just a new version of the same patch/commit"
