Input: move to use request_irq by IRQF_NO_AUTOEN flag
disable_irq() after request_irq() still has a time gap in which
interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will
disable IRQ auto-enable because of requesting.
On the other hand, request_irq() after setting IRQ_NOAUTOEN as
below
irq_set_status_flags(irq, IRQ_NOAUTOEN);
request_irq(dev, irq...);
can also be replaced by request_irq() with IRQF_NO_AUTOEN flag.
