From 4607d65ab3d80fe0e648e221f58b03b9ed051fdd Mon Sep 17 00:00:00 2001 From: Roland Stigge Date: Thu, 6 Sep 2012 11:39:10 +0200 Subject: ARM: LPC32xx: Use handle_edge_irq() callback on edge type irqs irq.c uses handle_level_irq() as the unconditional default handler. This patch uses handle_edge_irq() instead for edge type irqs.
