From 223ba92a80594ed6c071b39402660ee07937ac8a Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Fri, 23 Feb 2018 10:01:40 +0100 Subject: [PATCH] crypto: atmel-aes - fix the keys zeroing on errors [ Upstream commit 5d804a5157dbaa64872a675923ae87161165c66b ] The Atmel AES driver uses memzero_explicit on the keys on error, but the variable zeroed isn't the right one because of a typo. Fix this by using the right variable.
