From d271d077ac66e839a0f443f1089a0af1ef15fd51 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Fri, 25 Jan 2013 10:18:09 -0800 Subject: [PATCH] cpufreq: exynos: Fix unsigned variable being checked for negative value exynos_cpufreq_scale function returns signed value which was assigned to an unsigned variable and checked for negative value which is always false. Hence make it signed. Fixes the following smatch warnings: drivers/cpufreq/exynos-cpufreq.c:83 exynos_cpufreq_scale() warn: unsigned 'old_index' is never less than zero. drivers/cpufreq/exynos-cpufreq.c:89 exynos_cpufreq_scale() warn: unsigned 'index' is never less than zero.
