No, you are changing things between each version, hopefully based on the
review comments.  And the testing that is being provided for you showing
you where your code breaks the build.

That goes in the "what changed" lines, as is documented in the kernel
documentation.  Please follow that when resubmitting if you wish for
your changes to be able to be accepted.
