I think you send the very same series several times yesterday. Please check your
config and make sure that you don't send a series more then once. If for any
reason you have to resend the series then please specify in the cover letter why
you resend it.

Reviewing series can take a while, be patient. If nobody reacts to your series
you can send a reminder email (best if you just hit reply-all on the cover
letter) asking kindly for review. Sending out the same series on a daily or
hourly basis will most probably lead to confusion, as people don't know which
version is the "good" one. In the end it has the contrary affect from what you
want to achieve (getting someone to review your series).

Regards,
Matthias

sorry for the confusion.

there was some problem with my upstream account setting yesterday, the
first several letters was rejected by
"linux-arm-kernel@lists.infradead.org" and "devicetree@vger.kernel.org".

after the problem was fixed, i have resent the last one, which include
the key world "Resend first version".
