    SubjectRe: [PATCH v3 7/8] drm/mediatek: Add support for mediatek SOC MT2712
    Hi Stu,

    Thank you for the patch! Yet something to improve:

    [auto build test ERROR on drm/drm-next]
    [also build test ERROR on v4.17-rc6 next-20180517]
    [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/stu-hsieh-mediatek-com/Add-support-for-mediatek-SOC-MT2712/20180525-211114
    base: git://people.freedesktop.org/~airlied/linux.git drm-next
    config: arm-allmodconfig (attached as .config)
    compiler: arm-linux-gnueabi-gcc (Debian 7.2.0-11) 7.2.0
    reproduce:
    wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
    chmod +x ~/bin/make.cross
    # save the attached .config to linux build tree
