From cf22854cee10e16e28b1dde136c37e82b7d503ee Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 20 Mar 2009 15:21:02 +0200 Subject: [PATCH] OMAP3: PM: Added resched check into idle calls Fixes a bug where scheduling is delayed until next wakeup due to race condition (e.g. interrupt requests scheduling just before omap_sram_idle is entered.)
