    Subject[PATCH 9/9] PM: Revert "driver core: platform_bus: allow runtime override of dev_pm_ops"
    Date
    From: Kevin Hilman <khilman@ti.com>

    The platform_bus_set_pm_ops() operation is deprecated in favor of the
    new device power domain infrastructre implemented in commit
    7538e3db6e015e890825fbd9f8659952896ddd5b (PM: add support for device
    power domains)
