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. ./arch/arm/mach-bcm/platsmp-brcmstb.c:337:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 329, but without a corresponding object release within this function. ./arch/arm/mach-bcm/platsmp-brcmstb.c:341:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 329, but without a corresponding object release within this functio ./arch/arm/mach-bcm/bcm63xx_smp.c:150:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 130, but without a corresponding object release within this function.
