I had smtp mail server weirdness that led me to belive that the freescale.com
email addresses in this patch were causing the patch to not show up on the
mailing list, so I resent [PATCH 13/14] with the email address changed to
nxp.com.  Then both copies of [PATCH 13/14] showed up.  So please ignore
the duplicated email for this patch.  Both copies are identical and either
either freescale.com or nxp.com are ok for the email address.  nxp.com
version would be preferred I guess.

Thanks,
Stuart
