From 6d7bcb1464a89181ddc4b4584ad6e0c7566ae31b Mon Sep 17 00:00:00 2001 From: Xiaoguang Chen <chenxg@marvell.com> Date: Fri, 8 Nov 2013 13:23:52 +0800 Subject: [PATCH] cpufreq: conservative: set requested_freq to policy max when it is over policy max When requested_freq is over policy->max, set it to policy->max. This can help to speed up decreasing frequency. Signed-off-by: Xiaoguang Chen <chenxg@marvell.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
