From 152b28392a8d9dd08e789b48b602eb75eef436fa Mon Sep 17 00:00:00 2001 From: Nicholas Krause Date: Thu, 6 Aug 2015 13:05:54 -0400 Subject: [PATCH] KVM: s390: Fix assumption that kvm_set_irq_routing is always run successfully This fixes the assumption that kvm_set_irq_routing is always run successfully by instead making it equal to the variable r which we use for returning in the function kvm_arch_vm_ioctl instead of making r equal to zero when calling this particular function and incorrectly making the caller of kvm_arch_vm_ioctl think the function has run successfully.
