Thanks for the tweak. I overlooked the "Sign-off" part. I used "diff"
because of what BR's manual suggests [1]:

  If the software is under version control, it is recommended to use
  the upstream SCM software to generate the patch set.

  Otherwise, concatenate the header with the output of the
  diff -purN ...

The proposed patch was made for a tar ball release that is not under
any version control per se. With the hindsight, maybe I should have
checked for "v6.8.0" as branch/tag in upstream repo.

That extra change (setting "HOSTAR") is necessary, because in upstream
that was already taken care of before the patch submission. However, in
v6.8.0 release "HOSTAR" is never initialised and the fix is actually
using it.
