From 00420a65fa2beb3206090ead86942484df2275f3 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 27 Jan 2016 00:16:37 +0800 Subject: [PATCH] crypto: shash - Fix has_key setting The has_key logic is wrong for shash algorithms as they always have a setkey function. So we should instead be testing against shash_no_setkey.
