From 304ab886e2dc34e95e82727fa072275e67616230 Mon Sep 17 00:00:00 2001 From: Jouni Hogander Date: Fri, 16 May 2008 13:57:15 +0300 Subject: [PATCH] OMAP: Add new function to check wether there is irq pending Add common omap2/3 function to check wether there is irq pending. Switch to use it in omap2 pm code instead of its own.
