6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Miaoqian Lin linmq006@gmail.com
commit eb53368f8d6e2dfba84c8a94d245719bcf9ae270 upstream.
The of_find_node_by_name() function returns a device tree node with its reference count incremented. The caller is responsible for calling of_node_put() to release this reference when done.
Found via static analysis.
