[Qemu-devel] [PATCH v12 3/5] arm_kvm: Do not assume particular GIC type in kvm_arch_irqchip_create()

[Pavel Fedin <p.fedin@samsung.com>]

This allows to use different GIC types from v2. There are no kernels which
could advertise KVM_CAP_DEVICE_CTRL without the actual ability to create
GIC with it.
