6.18-stable review patch. If anyone has any objections, please let me know.

From: Haotian Zhang vulab@iscas.ac.cn
[ Upstream commit 6cdc4d488c2f3a61174bfba4e8cc4ac92c219258 ]
The device node pointers `np_conn` and `np_edev`, obtained from of_parse_phandle() and of_get_parent() respectively, are not released. This results in a reference count leak.
Add of_node_put() calls after the last use of these device nodes to properly release their references and fix the leaks.
