Initial patch is correct:

$ git show -U10 d84cc9c9524e
[...]
@@ -2802,21 +2802,20 @@ static struct talitos_alg_template driver_algs[] = {
        {       .type = CRYPTO_ALG_TYPE_ABLKCIPHER,

                        .cra_driver_name = "ecb-aes-talitos",

                        }
                },
[...]

and similar for ecb(des), ecb(des3_ede).

Current patch is incorrect: it adds ivsize for ecb and removes it from cbc.
