Date: Sun, 30 Jan 2011 20:29:38 +0100 From: Stefan Weil <weil@...l.berlios.de> To: Tony Lindgren <tony@...mide.com> Cc: Stefan Weil <weil@...l.berlios.de>, Russell King <linux@....linux.org.uk>, linux-omap@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH 19/23] arm: 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.
