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
