Subject: [PATCH 01/17] PM: EM: Refactor em_cpufreq_update_efficiencies() arguments
Date: Tue, 14 Mar 2023 10:33:41 +0000 [thread overview]
Message-ID: <20230314103357.26010-2-lukasz.luba@arm.com> (raw)
In-Reply-To: <20230314103357.26010-1-lukasz.luba@arm.com>
In order to prepare the code for the modifiable EM perf_state table,
refactor existing function em_cpufreq_update_efficiencies().
