[ Upstream commit 92606ec9285fb84cd9b5943df23f07d741384bfc ]
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/arm64/kernel/cpu_ops.c:102:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 69, but without a corresponding object release within this function.
