[PATCH v2 3/4] cpufreq: Add strict_target to struct cpufreq_policy
From: Rafael J. Wysocki
Date: Mon Nov 09 2020 - 11:57:11 EST
From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
Add a new field to be set when the CPUFREQ_GOV_FLAG_STRICT_TARGET
flag is set for the current governor to struct cpufreq_policy, so
that the drivers needing to check CPUFREQ_GOV_FLAG_STRICT_TARGET do
not have to access the governor object during every frequency
transition.
