Subject: Re: [PATCH 1/2 v2] drivers/base: Combine topology.c and cpu.c
Hi Prarit,
[auto build test ERROR on driver-core/driver-core-testing]
[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]
