genirq: Add irq_get_trigger_type() to get IRQ flags Drivers that want to get the trigger edge/level type flags for a given interrupt have to call irq_get_irq_data(irq) to get the struct irq_data and then irqd_get_trigger_type(irq_data) to obtain the IRQ flags. This is not only error prone but also unnecessary exposes the struct irq_data to callers. It's better to have an irq_get_trigger_type() function to obtain the edge/level flags for an IRQ.
