Let's avoid checking against kvm->arch.vpic. We have kvm->arch.irqchip_mode for that now. KVM_IRQCHIP_KERNEL implies a fully inititalized pic, while kvm->arch.vpic might temporarily be set but invalidated again if e.g. kvm_ioapic_init() fails when setting KVM_CREATE_IRQCHIP. Although current users seem to be fine, this avoids future bugs. Signed-off-by: David Hildenbrand <david@redhat.com> --- arch/x86/kvm/irq.h | 5 +---- 1 file changed, 1 insertion(+), 4 deletions(-)
