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/dir.c: In function 'ovl_rename':
fs/overlayfs/dir.c:1060:2: warning: 'newdentry' may be used uninitialized in this function [-Wmaybe-uninitialized]
  dput(newdentry);
  ^
fs/overlayfs/dir.c:1062:2: warning: 'olddentry' may be used uninitialized in this function [-Wmaybe-uninitialized]
  dput(olddentry);
  ^

Introduced by commit

  02cac3227a28 ("ovl: mark upper dir with type origin entries "impure"")
