Please align the arguments to the first argument of the first line and
use the 100 characters, i.e.

static int aplic_direct_irqdomain_translate(struct irq_domain *d, struct irq_fwspec *fwspec,
					    unsigned long *hwirq, unsigned int *type)
{

All over the place.

Variable ordering. Please make this consistent according to documentation.

I still have to understand that "reason". :)
