Yeah, looks good to me as well, thanks. The lm8323 change should be Acked 
by Dmitry though, as it's in his area.

[PATCH 00/13] leds: fix attribute-creation races

2014-06-25 Thread Johan Hovold
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.

Thanks a lot for driving this. I will applied this patchset into my
