cryptd_alloc_ablkcipher() will allocate a cryptd-ed ablkcipher for
specified algorithm name. The new allocated one is guaranteed to be
cryptd-ed ablkcipher, so the blkcipher underlying can be gotten via
cryptd_ablkcipher_child().

You need to check whether tfm is an error before dereferencing it.
Also it's

Why do we need this check? Someone else may register cryptd template?
Which error number should be return? -EINVAL?
-ENOMEM for example.
You mean something as follow:
if (crypto_ablkcipher_tfm(tfm)-__crt_alg-cra_module
