From d2641a5c3d5ecaa1078225e493c7fed821715a04 Mon Sep 17 00:00:00 2001 From: Ionela Voinescu Date: Mon, 14 Dec 2020 12:38:20 +0000 Subject: cppc_cpufreq: use policy->cpu as driver of frequency setting Considering only the currently supported coordination types (ANY, HW, NONE), this change only makes a difference for the ANY type, when policy->cpu is hotplugged out. In that case the new policy->cpu will be different from ((struct cppc_cpudata *)policy->driver_data)->cpu. While in this case the controls of *ANY* CPU could be used to drive frequency changes, it's more consistent to use policy->cpu as the leading CPU, as used in all other cppc_cpufreq functions. Additionally, the debug prints in cppc_set_perf() would no longer create confusion when referring to a CPU that is hotplugged out.
