[PATCH 4.14 136/496] kvm: fix warning for CONFIG_HAVE_KVM_EVENTFD builds

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sebastian Ott <sebott@xxxxxxxxxxxxxxxxxx>

[ Upstream commit 076467490b8176eb96eddc548a14d4135c7b5852 ]

Move the kvm_arch_irq_routing_update() prototype outside of
ifdef CONFIG_HAVE_KVM_EVENTFD guards to fix the following sparse warning:

arch/s390/kvm/../../../virt/kvm/irqchip.c:171:28: warning: symbol 'kvm_arch_irq_routing_update' was not declared. Should it be static?
