From 88056ec346ccf41f63dbc7080b24b5fd19d1358d Mon Sep 17 00:00:00 2001
From: Herbert Xu <herbert@gondor.apana.org.au>
Date: Tue, 14 Jul 2009 12:28:26 +0800
Subject: crypto: ahash - Convert to new style algorithms

This patch converts crypto_ahash to the new style.  The old ahash
algorithm type is retained until the existing ahash implementations
are also converted.  All ahash users will automatically get the
new crypto_ahash type.
