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.
