[PATCH 03/11] powerpc/powermac: add missing of_node_put

From: Julia Lawall
Date: Thu Sep 07 2023 - 13:15:38 EST


for_each_node_by_name performs an of_node_get on each
iteration, so a break out of the loop requires an
of_node_put.

This was done using the Coccinelle semantic patch
iterators/for_each_child.cocci
