[PATCH 03/17] 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.

[PATCH 03/17] 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.
