6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Carrasco javier.carrasco.cruz@gmail.com
commit e41d574b359ccd8d99be65c6f11502efa2b83136 upstream.
The fwnode_for_each_child_node() loop requires manual intervention to decrement the child refcount in case of an early return.
Add the missing calls to fwnode_handle_put(child) to avoid memory leaks in the error paths.
