From 8353584eae4af8f37e5a23b63ed816c79185a9c9 Mon Sep 17 00:00:00 2001 From: Stefan Weil Date: Sun, 30 Jan 2011 20:29:38 +0100 Subject: [PATCH] OMAP: PM: SmartReflex: Fix possible null pointer read access These errors were found by cppcheck: arch/arm/mach-omap2/smartreflex.c:784: error: Possible null pointer dereference: sr_info arch/arm/mach-omap2/smartreflex.c:799: error: Possible null pointer dereference: sr_info Both conditional statements are executed when sr_info == NULL, so accessing sr_info->voltdm would fail.
