6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Carrasco javier.carrasco.cruz@gmail.com
commit 5beb6fba25db235b52eab34bde8112f07bb31d75 upstream.
Error paths that exit for_each_child_of_node() need to call of_node_put() to decerement the child refcount and avoid memory leaks.
Add the missing of_node_put().
