From 6e8d8ecf438792ecf7a3207488fb4eebc4edb040 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 11 Jan 2016 21:29:41 +0800 Subject: [PATCH] crypto: algif_skcipher - Add key check exception for cipher_null This patch adds an exception to the key check so that cipher_null users may continue to use algif_skcipher without setting a key.
