Subject: [PATCH V2 07/11] cpufreq: Use cpufreq_policy_list for iterating over policies
Date: Tue,  6 Aug 2013 22:53:09 +0530	[thread overview]
Message-ID: <e54ce908bb964d643a2bbb945ed4a8dcb3ea00bf.1375809311.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1375809311.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1375809311.git.viresh.kumar@linaro.org>

For iterating over all policies currently we are iterating over all CPUs and
then finding their policies. Lets use the newly created infrastructure
cpufreq_policy_list.
