From 0435d47e2627b76b6dfb59e2e95ffed7232bd0ed Mon Sep 17 00:00:00 2001 From: Iuliana Prodan Date: Wed, 31 Jul 2019 16:08:15 +0300 Subject: [PATCH] crypto: caam - change return value in case CAAM has no MDHA To be consistent with other CAAM modules, caamhash should return 0 instead of -ENODEV in case CAAM has no MDHA. Based on commit 1b46c90c8e00 ("crypto: caam - convert top level drivers to libraries") the value returned by entry point is never checked and the exit point is always executed.
