From 0343371e22dcfec9291193ad3e771dbce3a93670 Mon Sep 17 00:00:00 2001 From: Kalle Jokiniemi Date: Fri, 26 Sep 2008 11:04:20 +0300 Subject: [PATCH] OMAP3: PM: CPUidle: fix init sequencing Previously omap3_idle_init() was called in device_init, while omap_pm_init() is called at late_initcall. This causes the cpu idle driver to call omap_sram_idle before it is properly initialized. This patch fixes the issue by moving omap3_idle_init into omap3_pm_init.
