crypto: Add a report function pointer to crypto_type
We add a report function pointer to struct crypto_type. This function pointer is used from the crypto userspace configuration API to report crypto algorithms to userspace. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
