From 72bb2fcd23afe8db53b47e8f9edd736c517ba532 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 9 Feb 2010 10:33:03 +0800 Subject: KVM: cleanup the failure path of KVM_CREATE_IRQCHIP ioctrl If we fail to init ioapic device or the fail to setup the default irq routing, the device register by kvm_create_pic() and kvm_ioapic_init() remain unregister. This patch fixed to do this.
