genirq: Mirror irq trigger type bits in irq_data.state
That's the data structure chip functions get provided. Also allow them to signal the core code that they updated the flags in irq_data.state by returning IRQ_SET_MASK_OK_NOCOPY. The default is unchanged. The type bits should be accessed via: val = irqd_get_trigger_type(irqdata); and irqd_set_trigger_type(irqdata, val); Coders who access them directly will be tracked down and slapped with stinking trouts. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
