From ba6a98fe79b416541d11d6d4a89ba8d86b5409a2 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Wed, 12 Jun 2019 15:33:05 +0200 Subject: [PATCH] s390/crypto: prng: Use -ENODEV instead of -EOPNOTSUPP Let's use the error value that is typically used if HW support is not available when trying to load a module - this is also what systemd's systemd-modules-load.service expects.
