From b24a5b6512a6fb89f3b99b9b0f829b4448e62db0 Mon Sep 17 00:00:00 2001 From: Saravana Kannan Date: Thu, 27 Feb 2014 17:58:34 -0800 Subject: [PATCH] cpufreq: stats: Remove redundant cpufreq_cpu_get() call __cpufreq_stats_create_table always gets pass the valid and real policy struct. So, there's no need to call cpufreq_cpu_get() to get the policy again. Acked-by: Viresh Kumar Signed-off-by: Saravana Kannan Signed-off-by: Rafael J.
