    SubjectRe: [PATCH v4 2/2] fpga: Add support for Lattice iCE40 FPGAs
    Hi Joel,

    [auto build test ERROR on linus/master]
    [also build test ERROR on v4.9-rc3 next-20161028]
    [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]

    config: powerpc-allmodconfig (attached as .config)
    compiler: powerpc64-linux-gnu-gcc (Debian 6.1.1-9) 6.1.1 20160705
    reproduce:
    wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
    chmod +x ~/bin/make.cross
    # save the attached .config to linux build tree
    make.cross ARCH=powerpc

    All errors (new ones prefixed by >>):
