[PATCH v1 1/2] uio: uio_dmem_genirq: Make use of irq_get_trigger_type()

From: Vasileios Amoiridis
Date: Thu Sep 12 2024 - 19:59:54 EST


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.
