[PATCH] irqchip: mips-cpu: Remove eoi operation

From: Jiaxun Yang
Date: Mon Jan 13 2020 - 05:13:18 EST


The eoi opreation in mips_cpu_irq_controller caused chained_irq_enter
falsely consider CPU IP interrupt as a FastEOI type IRQ. So the interrupt
won't be masked during in handler. Which might lead to spurious interrupt.

Thus we simply remove eoi operation for mips_cpu_irq_controller,
