From 13f678894bd0112582ea26e9b98db5118150d6a9 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Tue, 18 Feb 2020 13:07:17 -0800 Subject: KVM: Don't free new memslot if allocation of said memslot fails The two implementations of kvm_arch_create_memslot() in x86 and PPC are both good citizens and free up all local resources if creation fails. Return immediately (via a superfluous goto) instead of calling kvm_free_memslot(). Note, the call to kvm_free_memslot() is effectively an expensive nop in this case as there are no resources to be freed. No functional change intended.
