X.509: Fix error code in x509_cert_parse()
We forgot to set the error code on this path so it could result in returning NULL which leads to a NULL dereference. Fixes: db6c43bd2132 ("crypto: KEYS: convert public key and digsig asym to the akcipher api") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
