    SubjectDeprecate suspend/resume in device_driver
    From
    The suspend/resume will not be called if they are defined in
    device_driver directly,
    PM core will only use suspend/resume function in dev_pm_ops. Thus we shall
    mark the old suspend/resume deprecated and make them scheduled for removal.

    Subject: [PATCH] PM: Deprecate suspend/resume in device_driver

    Make suspend/resume callbacks in device_driver deprecated and scheduled
    for removal since they are not used in PM core anymore.

    Legacy drivers who still use them need to move suspend/resume callbacks
    to dev_pm_ops.
