[ Upstream commit 75eac7b5f68b0a0671e795ac636457ee27cc11d8 ]
The call to of_get_child_by_name returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
Detected by coccinelle with the following warnings:
./drivers/net/ethernet/ti/netcp_ethss.c:3661:2-8: ERROR: missing of_node_put;
acquired a node pointer with refcount incremented on line 3654, but without a
corresponding object release within this function.
