crypto: talitos - consolidate common cra_* assignments
Browse files Browse the repository at this point in the history 
the entry points and geniv definitions for all aead,
ablkcipher, and hash algorithms are all common; move them to a
single assignment in talitos_alg_alloc().

This assumes it's ok to assign a setkey() on non-hmac algs.
