From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 57cb17e764ba0aaa169d07796acce54ccfbc6cae upstream.
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")
