LED-class device attributes should be created using the attribute groups of struct device, rather than be added manually after the device has been registered in order to avoid racing with userspace. The first patch adds an attribute groups field to struct led_classdev, which is used during registration to add device attributes in a race-free manner. The remaining patches convert the current racy LED-device attribute creations to use the new facility. Hopefully my grep-patterns have caught most instances. Note that this also tends to simplify probe error paths. The lp55xx-common failed to remove the attribute group it is currently creating, something which is fixed separately. Note that this series include one driver from drivers/input/keyboard. The individual led-driver patches have been compile tested only.
