[Xen-devel] [PATCH v4 1/8] ARM: VGIC: drop unneeded gic_restore_pending_irqs()

[Andre Przywara <andre.przywara@xxxxxxx>]

In gic_restore_pending_irqs() we push our pending virtual IRQs into the
list registers. This function is called once from gic_inject(), just
before we return to the guest, but also in gic_restore_state(), when
we context-switch a VCPU. Having a closer look it turns out that the
later call is not needed, since we will always call gic_inject() anyway.
So remove that call (and the forward declaration) to streamline this
interface and make separating the GIC from the VGIC world later.
