From 1dacf194b1468546a5715db58cbb65d50b598482 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 24 Oct 2014 13:59:16 +0200 Subject: irqchip: irq-armada-370-xp: Use proper return value for ->set_affinity() The ->set_affinity() hook of 'struct irq_chip' is supposed to return one of IRQ_SET_MASK_OK or IRQ_SET_MASK_OK_NOCOPY. However, the code currently simply returns 0. This patch fixes that by using IRQ_SET_MASK_OK, which tells the IRQ core that it is responsible for updating irq_data.affinity. Note that this patch does not cause any change to the compiled code, as IRQ_SET_MASK_OK has the value 0. This is therefore just a simple cleanup.
