Subject: Re: [PATCH]: Fix ALIGN() macro

Hi:

OK I think I've found the problem.

[CRYPTO] hmac: Fix hmac_init update call

The crypto_hash_update call in hmac_init gave the number 1
instead of the length of the sg list in bytes.  This is a
missed conversion from the digest => hash change.

As tcrypt only tests crypto_hash_digest it didn't catch this.

Cheers,
