[PATCH v2 1/6] irqchip/stm32-exti: Fix irq_set_affinity return value

[Antonio Borneo]

From: Ludovic Barre <ludovic.barre@xxxxxxxxxxx>

When there is no parent, there is no specific action to do in
stm32-exti irqchip. In such case, it's incorrect returning an
error.

Let irq_set_affinity to return IRQ_SET_MASK_OK_DONE when there is
no parent.
