From 7db6a7fa09884b34d2a5d4e6e4ed58664a5f0cf8 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Tue, 12 Apr 2011 18:39:39 +0800 Subject: ARM: pxa: convert incorrect IRQ_TO_IRQ() to irq_to_gpio() This fixes the failure to register the IRQ_RTCAlrm alarm as a wakeup event. It is misinterpreted as a gpio irq not a PWER bitmask. Fixed this by converting the incorrect IRQ_TO_IRQ() to a correct version of irq_to_gpio().
