This, in tandem with dynamic debug, can print useful information about
-EPROBE_DEFFER like below, and keeps similar behavior for other errors:

    [   16.561072] cpu cpu0: error -EPROBE_DEFER: dev_pm_opp_of_find_icc_paths: Unable to get path0
    [   16.575777] platform 18591000.cpufreq: deferred probe pending
