Hi Vadim,

[auto build test ERROR on platform-drivers-x86/for-next]
[also build test ERROR on next-20161027]
[cannot apply to v4.9-rc2]
[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]
[Check https://git-scm.com/docs/git-format-patch for more information]
