From 187999119d93f584209400b052cf092141a33650 Mon Sep 17 00:00:00 2001 From: Vaibhav Hiremath Date: Wed, 9 May 2012 10:07:05 -0700 Subject: ARM: OMAP1: Add checks for possible error condition in timer_init On OMAP1, omap_32k_timer_init() function always returns "true", irrespective of whether error occurred while initializing 32k sync counter as a kernel clocksource or not and execution will never fallback to mpu_timer clocksource init code. This patch adds check for return value from function omap_init_clocksource_32k(), and fallback to omap_mpu_timer_init() in case of failure/error from omap_init_clocksource_32k().
