parentcrypto: algapi - fold crypto_init_spawn() into crypto_grab_spawn() (diff)
crypto: hash - add support for new way of freeing instances
Add support to shash and ahash for the new way of freeing instances (already used for skcipher, aead, and akcipher) where a ->free() method is installed to the instance struct itself. These methods are more strongly-typed than crypto_template::free(), which they replace. This will allow removing support for the old way of freeing instances.
