Hi Nicholas, [auto build test ERROR on asm-generic/master] [also build test ERROR on v4.8-rc7 next-20160920] [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]
