From 25a3c5af57db0319f5cfb4c439efbc78b230599e Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Wed, 27 May 2015 10:04:56 +0200 Subject: s390/sclp: move sclp_execute related functions into the SCLP class Let's move the sclp_execute related functions into the SCLP class and pass the device state as parameter, so we have easy access to the SCLPDevice later on.
