Set the NOAUTOEN flag so the interrupt is not automatically enabled in setup_irq() Signed-off-by: Thomas Gleixner Acked-by: Nicolas Pitre Signed-off-by: Russell King --- diff --git a/arch/arm/mach-pxa/mainstone.c b/arch/arm/mach-pxa/mainstone.c index 98356f81000..02e188d98e7 100644 --- a/arch/arm/mach-pxa/mainstone.c +++ b/arch/arm/mach-pxa/mainstone.c @@ -95,7 +95,10 @@ static void __init mainstone_init_irq(void) for(irq = MAINSTONE_IRQ(0); irq <= MAINSTONE_IRQ(15); irq++) { set_irq_chip(irq, &mainstone_irq_chip); set_irq_handler(irq, do_level_IRQ); - set_irq_flags(irq, IRQF_VALID | IRQF_PROBE); + if (irq == MAINSTONE_IRQ(10) || irq == MAINSTONE_IRQ(14)) + set_irq_flags(irq, IRQF_VALID | IRQF_PROBE | IRQF_NOAUTOEN); + else + set_irq_flags(irq, IRQF_VALID | IRQF_PROBE); } set_irq_flags(MAINSTONE_IRQ(8), 0); set_irq_flags(MAINSTONE_IRQ(12), 0);
