CVE-2021-47260 — NFS: Fix a potential NULL dereference in nfs_get_client()

Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

NFS: Fix a potential NULL dereference in nfs_get_client()

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.
