Subject: [PATCH -next] net: netcp: add missing of_node_put() in netcp_probe()

From: Wei Yongjun <weiyongjun1@...wei.com>

This node pointer is returned by of_get_child_by_name() with refcount
incremented in this function. of_node_put() on it before exitting this
function.

This is detected by Coccinelle semantic patch.
