[PATCH v2 1/3] cpufreq: Export acpu_cpufreq_exit for other drivers to call
From: Mario Limonciello
Date: Mon Mar 28 2022 - 22:00:10 EST
Currently, the only way to load an alternative cpufreq driver is to unload
acpi-cpufreq first.
Loosen that restriction to allow other kernel modules to unregister a
registered driver.
