Convert the following case:

        struct irq_data *irq_data = irq_get_irq_data(irq);

        if (irq_data && irqd_get_trigger_type(irq_data) ... ) {
                ...
        }

to the simpler:

        if (irq_get_trigger_type(irq) ... ) {
                ...
        }

by using the irq_get_trigger_type() function.

Btw, can you add a coccinelle ruleset for this?
