[Xen-devel] [PATCH v4 4/6] xen: arm: drop redundant extra call to vgic_reserve_virq

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

This is only needed if we are giving the IRQ to dom0 (as opposed to
setting it up for passthrough due to xen,passthrough property). There
is already a call to vgic_reserve_virq inside the if ( need_mapping ),
so drop this one.
