at86rf230: rework irq_pol setting
This patch rework the irq_pol register setting for rising and falling interrupt settings only. The default behaviour should be rising flag. Also use IRQ_TYPE_* defines instead of IRQF_* defines. There is no functionality change but irq_get_trigger_type returns IRQ_TYPE_* defines. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
