From: Dan Carpenter <dan.carpenter@oracle.com> [ Upstream commit 09226e8303beeec10f2ff844d2e46d1371dc58e0 ] None of the callers are expecting NULL returns from nfs_get_client() so this code will lead to an Oops. It's better to return an error pointer. I expect that this is dead code so hopefully no one is affected.
