6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Javier Carrasco <javier.carrasco.cruz@xxxxxxxxx>
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.
