This is not a RESEND, it is a new version.  From Documentation/process/submitting-patches.rst:

  Don't add "RESEND" when you are submitting a modified version of your
  patch or patch series - "RESEND" only applies to resubmission of a
  patch or patch series which have not been modified in any way from the
  previous submission.

And the "in any way" really does mean in _any_ way.  E.g. if a patch is rebased,
the version needs to be bumped.  RESEND should only ever be used when sending
literally the same patch/email file, e.g. if something went awry in the delivery
of the email, or you forgot to Cc the right people, tec.

Wrap closer to ~75 chars, wrapping at ~55 is too aggressive.

Vipin provided his Reviewed-by, that should have been captured here.  Please read
through Documentation/process/submitting-patches.rst, guidance on "using" the
various tags is also provided there.  And if you have time, pretty much all of
Documentation/process/ is worth reading.

No need to send a new version, all of this is easy to fixup when applying.
