[kbuild test robot]

Hi Christian,

I love your patch! Perhaps something to improve:

[auto build test WARNING on v4.15-rc5]
[also build test WARNING on next-20180104]
[cannot apply to swiotlb/linux-next]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)


Please review and possibly fold the followup patch.
