From 500b3e3c3dc8e4845b77ae81e5b7b085ab183ce6 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 14 Jul 2009 20:29:57 +0800 Subject: [PATCH] crypto: ahash - Remove old_ahash_alg Now that all ahash implementations have been converted to the new ahash type, we can remove old_ahash_alg and its associated support.
