In the previous revision you have got the Reviewed-by tag, which you
didn't include here for some reason.


This revision is:

Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

Note, there is no need to send a next iteration just for these tags.
They usually get picked up by the patch management software (including
the Fixes tag).
