Calling device_add causes an inital uevent for that device to be generated. The power_supply uevent function calls the drivers get_property function, which might causes the driver to update its state, which again might causes the driver to call power_supply_changed(). Since the power_supplys changed_work has not been initialized at this point the behavior is undefined and can result in an OOPS. This patch fixes the issue by initializing the power_supplys changed_work prior to adding the power_supplys device to the device tree.
