From 71fb165e23e3b66e68ca7baab6c317c2663c32d5 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 8 Feb 2023 15:01:01 +0100 Subject: KVM: s390: Use "int" as return type for kvm_s390_get/set_skeys() These two functions only return normal integers, so it does not make sense to declare the return type as "long" here.
