    HSI: omap_ssi: Fix refcount leak in ssi_probe
    
    [ Upstream commit 9a2ea132df860177b33c9fd421b26c4e9a0a9396 ]
    
    When returning or breaking early from a
    for_each_available_child_of_node() loop, we need to explicitly call
    of_node_put() on the child node to possibly release the node.
