If anyone has any objections, please let me know. ------------------ From: Felix Gu [ Upstream commit 584b457f4166293bdfa50f930228e9fb91a38392 ] The serdes device_node is obtained using of_get_child_by_name(), which increments the reference count. However, it is never put, leading to a reference leak. Add the missing of_node_put() calls to ensure the reference count is properly balanced.
