Subject: [PATCH 2/2] aes_s390: access fallback.cip cipher fallback mode
|The fallback code in cipher mode touch the union fallback.blk instead
|of fallback.cip. This is wrong because we use the cipher and not the
|blockcipher. This did not show any side effects yet because both types /
|structs contain the same element right now.
