Subject: [PATCH 21/26] cpu_cooling: create list of cpufreq_cooling_devices
Date: Fri, 28 Nov 2014 15:14:15 +0530 [thread overview]
Message-ID: <451cea6e5f417b0e76747ea8d8f3aa852f8bbf54.1417167599.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>
That will be used by later patches to iterate over all cpufreq cooling devices.
