This looks fine, if you resubmit, can you add a missing space between "adding" and "missing"? This applies to all of your patches, so I am assuming you somehow scripted that, which should be easy to fix. With that changed: Reviewed-by: Florian Fainelli <f.fainelli@gmail.com>

The call to of_get_next_child returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./arch/arm/mach-bcm/board_bcm281xx.c:43:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 35, but without a corresponding object release within this function.
