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

[Stephen Rothwell]

Hi,

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

fs/nfsd/nfs4state.c: In function 'copy_cred':
fs/nfsd/nfs4state.c:1917:6: warning: unused variable 'ret' [-Wunused-variable]
  int ret;
      ^

Introduced by commit

  d39662236bf8 ("nfsd4: remove pointless strdup_if_nonnull")

Also, that commit has no Signed-off-by from its Author.
