Hi Arnd,

[auto build test ERROR on scsi/for-next]
[also build test ERROR on v4.7 next-20160802]
[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/Arnd-Bergmann/bfa-fix-W-1-build-warnings/20160803-122019
base:   https://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi.git for-next
config: xtensa-allmodconfig (attached as .config)
compiler: xtensa-linux-gcc (GCC) 4.9.0
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=xtensa 

Note: the linux-review/Arnd-Bergmann/bfa-fix-W-1-build-warnings/20160803-122019 HEAD 6b97e29875c21d79abdc2be27ed0d7edb05dff6a builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
