irqchip/irq-csky-mpintc: Remove unnecessary loop in interrupt handler (e85c9c90) · Commits · 戴 / test

csky_mpintc_handler() ->handle_domain_irq() ->irq_exit() ->invoke_softirq() ->__do_softirq() ->local_irq_enable() If new interrupt coming, it'll get into interrupt trap before return to csky_mpintc_handler(). So there is no need loop in csky_mpintc_handler. Signed-off-by:
