From 5c98d62059faf7c59211cb591da671eaac7b7c3c Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 28 May 2015 22:07:55 +0800 Subject: crypto: aead - Add aead_alg_instance Now that type-safe init/exit functions exist, they often need to access the underlying aead_instance. So this patch adds the helper aead_alg_instance to access aead_instance from a crypto_aead object.
