[kbuild test robot <lkp@intel.com>]

Hi Rahul,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on net-next/master]

url:    https://github.com/0day-ci/linux/commits/Rahul-Lakkireddy/cxgb4-rework-on-chip-memory-read/20180116-050826
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)
