    SubjectRe: [PATCH] PM: EM: do not allow pd creation prior to debugfs initialization
    From
    Date
    Thanks Lukasz for comment.
    For any reason (ex: HW dependency, etc), if  init_call level of cpufreq/devfreq driver changed
    prior to fs_init call, we would land there right?

    One of such example is, 'drivers/cpufreq/qcom-cpufreq-hw.c' uses postcore_initcall().

    Thanks,
    Chandrasekhar L
