Hi Jann,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on security/next]
[also build test WARNING on v4.19-rc5 next-20180928]
[if your patch is applied to the wrong git tree, please drop us a note to help 
improve the system]

This looks to me as if something went very wrong in the 0day test bot;
the warnings below don't have anything to do with my patch, as far as
I can tell, and the "TO:" and "CC:" lines at the bottom of this
message are also entirely unrelated.

Thanksfor your reminding. The robot merged the patch
based on an quite old branch, so these warnings are not from this patch.

Best Regards,
Rong Chen
