From 4e1d14bcd10a33537918a9a747ab90fc5c2e6d7f Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 3 Jan 2018 11:16:28 -0800 Subject: crypto: ghash - remove checks for key being set Now that the crypto API prevents a keyed hash from being used without setting the key, there's no need for GHASH to do this check itself.
