From eb608521f1e25a8c14295b6d9a3853c3cd8c6cf8 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Tue, 6 Aug 2013 22:53:09 +0530 Subject: [PATCH] cpufreq: Use cpufreq_policy_list for iterating over policies To iterate over all policies we currently iterate over all CPUs and then get the policy for each of them. Let's use the newly created cpufreq_policy_list for this purpose. [rjw: Changelog] Signed-off-by: Viresh Kumar Signed-off-by: Rafael J.
