The EM is registered by cpufreq drivers (or devfreq), which is later
than fs_initcall, so the debugfs is setup. We even have added recently
a dedicated callback into the cpufreq (register_em()) for that.

Do you have such code which registers EM for CPUs (or some devfreq)
earlier than this fs_initcall?

I cannot find such code in mainline.
