From 9b97e9f555f1fe5044dc76d9212078757aa143ce Mon Sep 17 00:00:00 2001 From: Harald Freudenberger Date: Fri, 17 Aug 2018 09:01:09 +0200 Subject: [PATCH] s390/zcrypt: switch return type to bool for ap_instructions_available() Function ap_instructions_available() had returntype int but in fact returned 1 for true and 0 for false. Changed returntype to bool.
