From f2a25160887e00434ce1361007009120e1fecbda Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Thu, 4 Sep 2014 21:13:33 +0200 Subject: [PATCH] KVM: remove redundant assignments in __kvm_set_memory_region __kvm_set_memory_region sets r to EINVAL very early. Doing it again is not necessary. The same is true later on, where r is assigned -ENOMEM twice.
