Again, please stop.

I have told you, and others who are purporting to send patches from ZTE
to please stop using gmail.com addresses as there is no way to verify
that you really are from ZTE.  You are potentially lying about who you
are here, which is not allowed in kernel development for obvious
reasons.

Also, these email addresses are "one way only" with no responses ever
being recieved, and so they have been banned from vger mailing lists.

I will go ask this one to be banned as well.

Please work with your employer to get their email settings fixed up so
that you can properly send patches.  Do NOT abuse gmail for this as
that's not ok.
