    Subject[PATCH] driver core: Move device_links_purge() after bus_remove_device()
    Date
    Currently we are unbinding device link consumers when detaching the
    supplier. So we need to make sure the detaching happens before purging
    the supplier's device links.

    Move device_links_purge() after bus_remove_device() in device_del()
    for that.
