In short, the cpufrequ_governor sysfs interface is not available after
your commit.  Caused ACPI cpufreq driver to stop working?

To reproduce:

        git clone git://git.kernel.org/pub/scm/linux/kernel/git/wfg/lkp-tests.git
        cd lkp-tests
        bin/lkp install job.yaml  # job file is attached in this email
        bin/lkp run     job.yaml

design or configuration may affect actual performance.
