[kbuild test robot]

Hi Boris,

[auto build test ERROR on next-20151127]
[cannot apply to mtd/master v4.4-rc3 v4.4-rc2 v4.4-rc1 v4.4-rc3]

url:    https://github.com/0day-ci/linux/commits/Boris-Brezillon/mtd-nand-refactor-the-NAND-subsystem-part-1/20151201-190822
config: arm-imx_v6_v7_defconfig (attached as .config)
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=arm
