    SubjectRe: [PATCH 1/3] crypto: Change lz4 modules to work with new lz4 compressor module version
    Hi Sven,

    [auto build test ERROR on linus/master]
    [also build test ERROR on next-20161221]
    [cannot apply to v4.9]
    [if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

    url: https://github.com/0day-ci/linux/commits/Sven-Schmidt/Update-LZ4-compressor-module/20161221-130109
    config: i386-randconfig-x003-201651 (attached as .config)
    compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
    reproduce:
    # save the attached .config to linux build tree
    make ARCH=i386

    Note: the linux-review/Sven-Schmidt/Update-LZ4-compressor-module/20161221-130109 HEAD 08652114d6d8867d2e8b3545b5e9f8a2fe11a5d7 builds fine.
    It only hurts bisectibility.
