    ACPI: AC: Properly notify powermanagement core about changes
    
    [ Upstream commit ac62f52138f752d6c74adc6321e4996d84caf5bb ]
    
    The powermanagement core does various actions when a powersupply changes.
    It calls into notifiers, LED triggers, other power supplies and emits an uevent.
    
    To make sure that all these actions happen properly call power_supply_changed().
