base:   https://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git libnvdimm-for-next
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

quoted

drivers/nvdimm/of_nvdimm.c:18:30: sparse: symbol 'bus_desc' was not declared. Should it be static?

   drivers/nvdimm/of_nvdimm.c:19:19: sparse: symbol 'bus' was not declared. Should it be static?

Please review and possibly fold the followup patch.
