KEYS: Fix an error code in request_master_key()
This function has two callers and neither are able to handle a NULL return. Really, -EINVAL is the correct thing return here anyway. This fixes some static checker warnings like: security/keys/encrypted-keys/encrypted.c:709 encrypted_key_decrypt() error: uninitialized symbol 'master_key'. Fixes: 7e70cb497850 ("keys: add new key-type encrypted") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Mimi Zohar <zohar@linux.vnet.ibm.com> Signed-off-by: James Morris <james.l.morris@oracle.com>
