This behavior was intentional. If you don't want the CC applied to the
entire series, you can just use git-send-email as this is its behavior.
In particular, it doesn't apply any of the addresses from the patches to
the cover letter, which was my primary objection.

If you would like to modify this patch to apply the entire CC list to
the cover letter, then I think you'll have addressed both of our
concerns and I'll add my Acked-by. As it is, please do not accept this
patch. I will nack it for poky and we don't want the two to diverge.

Please include the primary author/maintainer of sources/recipes/etc. on
CC.

Thanks,
