Thanks for the patch!

It should have its own type so that we get compiler type checking.
Something like,
struct cryptd_ablkcipher {
struct crypto_ablkcipher *cipher;
};

We should also check that the new tfm's module matches ours, i.e.,
crypto_ablkcipher_tfm(cipher)->__crt_alg->cra_module ==
THIS_MODULE
Granted this doesn't do much if we're built-in but it's better
than nothing.
Cheers,
