base:   https://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs.git dev-test
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

   fs/f2fs/node.c:486:15: sparse: expression using sizeof(void)
   fs/f2fs/node.c:1744:28: sparse: expression using sizeof(void)
>> fs/f2fs/node.c:2034:6: sparse: symbol 'load_nat_block' was not declared. Should it be static?
   fs/f2fs/node.c:2428:27: sparse: expression using sizeof(void)
   fs/f2fs/node.c:2523:40: sparse: restricted __le32 degrades to integer

Please review and possibly fold the followup patch.
