Rafael J. Wysocki c3ca81e81a driver core: Extend device_is_dependent() ... commit 3d1cf435e201d1fd63e4346b141881aed086effd upstream. If the device passed as the target (second argument) to device_is_dependent() is not completely registered (that is, it has been initialized, but not added yet), but the parent pointer of it is set, it may be missing from the list of the parent's children and device_for_each_child() called by device_is_dependent() cannot be relied on to catch that dependency. For this reason, modify device_is_dependent() to check the ancestors of the target device by following its parent pointer in addition to the device_for_each_child() walk.
