For example, the Synopsys DesignWare APB interrupt controller (dw_apb_ictl) is used as the secondary interrupt controller on arc, csky, arm64, and most arm32 SoCs, and it's also used as the primary interrupt controller on Hisilicon SD5203 (an arm32 SoC). The latter need to use set_handle_irq() to register the top-level IRQ handler, but this multi irq handler registration mechanism is not implemented on arc system. The input parameter "handle_irq" maybe defined as static and only set_handle_irq() references it. This will trigger "defined but not used" warning. So add "(void)handle_irq" to suppress it.
