From d5e4aaefd99797929e4455db48d8f9a8728f05f4 Mon Sep 17 00:00:00 2001 From: Lee Nipper Date: Wed, 19 May 2010 19:18:38 +1000 Subject: crypto: talitos - prepare for adding ahash algorithms No functional changes. Use a union in talitos_alg_template for the crypto_alg so that we can add a member later for ahash_alg.
