Hi Masahiro,

[auto build test ERROR on linus/master]
[also build test ERROR on v4.8-rc5 next-20160909]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]
[Suggest to use git(>=2.9.0) format-patch --base=<commit> (or --base=auto for convenience) to record what (public, well-known) commit your patch series was built on]
