From: Dan Carpenter <dan.carpenter@oracle.com>
[ Upstream commit 662f9a105b4322b8559d448f86110e6ec24b8738 ]
If xdr_inline_decode() fails then we end up returning ERR_PTR(0). The caller treats NULL returns as -ENOMEM so it doesn't really hurt runtime, but obviously we intended to set an error code here.
