From a8e70a1a4fd6c0bc634a2b3f7b4b77ee378c3134 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 11 Jan 2016 21:29:41 +0800 Subject: crypto: algif_skcipher - Add key check exception for cipher_null commit 6e8d8ecf438792ecf7a3207488fb4eebc4edb040 upstream. This patch adds an exception to the key check so that cipher_null users may continue to use algif_skcipher without setting a key.
