linux-next: build warning after merge of the overlayfs tree

[Stephen Rothwell]

Hi Miklos,

After merging the overlayfs tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/overlayfs/super.c: In function 'ovl_fill_super':
fs/overlayfs/super.c:1070:25: warning: 'numlower' may be used uninitialized in this function [-Wmaybe-uninitialized]
  unsigned int stacklen, numlower, i;
                         ^
fs/overlayfs/super.c:1069:15: warning: 'stack' may be used uninitialized in this function [-Wmaybe-uninitialized]
  struct path *stack;
               ^
