Subject: [PATCH 18/26] cpu_cooling: Merge get_cpu_frequency() into cpufreq_set_cur_state()
Date: Fri, 28 Nov 2014 15:14:12 +0530 [thread overview]
Message-ID: <7b0ee76e42a06e915d4699b2ff83fdf12f7b1543.1417167599.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1417167599.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1417167599.git.viresh.kumar@linaro.org>
get_cpu_frequency() is used from only one place, i.e. cpufreq_set_cur_state().
And there is no need to have this extra level of function calls. Merge them.
