5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Carrasco javier.carrasco.cruz@gmail.com
commit 362f1bf98a3ecb5a2a4fcbdaa9718c8403beceb2 upstream.
The for_each_child_of_node() loop requires explicit calls to of_node_put() to decrement the child's refcount upon early exits (break, goto, return).
Add the missing calls in the two early exits before the goto instructions.
