The only time we use the int_combiner_irq[] and ext_combiner_irq[] arrays in the Exynos4210Irq struct is during realize of the SoC -- we initialize them with the input IRQs of the combiner devices, and then connect those to outputs of other devices in exynos4210_init_board_irqs(). Now that the combiner objects are easily accessible as s->int_combiner and s->ext_combiner we can make the connections directly from one device to the other without going via these arrays. Since these are the only two remaining elements of Exynos4210Irq, we can remove that struct entirely.
