From be49e3465f222b4b796be8a21d14afbfd8f5d20f Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Wed, 2 Oct 2013 14:13:19 +0530 Subject: [PATCH] cpufreq: add new routine cpufreq_verify_within_cpu_limits() Most of the users of cpufreq_verify_within_limits() calls it for limiting with min/max from policy->cpuinfo. We can make that code simple by introducing another routine which will do this for them automatically. This patch adds another routine cpufreq_verify_within_cpu_limits() and updates others to use it.
