From 709ecc101aea53d3625b688697b7c9dc4235716d Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Mon, 27 May 2019 16:50:56 +0200 Subject: [PATCH] crypto: inside-secure - remove useless check When sending an ahash request, the code checks for the extra variable not to be 0. This check is useless as the extra variable can't be 0 at this point (it is checked on the line just before). This patch does not modify the driver behaviour in any way.
