[kbuild test robot]

Hi Daniel,

FYI, the error/warning still remains.

tree:   https://github.com/Xilinx/linux-xlnx master
head:   50dbfdba9101210db33a5a311b85a7409ab62278
commit: 472236088ad190937efa1be2d96965f9bb7c9bcb [688/744] kbuild: Add option to turn incompatible pointer check into error
config: i386-allmodconfig (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
        git checkout 472236088ad190937efa1be2d96965f9bb7c9bcb
        # save the attached .config to linux build tree
        make ARCH=i386 

All errors (new ones prefixed by >>):
