4.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx> commit 277867ade8262583f4280cadbe90e0031a3706a7 upstream. of_find_compatible_node() is calling of_node_put() on its first argument thus leading to an unbalanced of_node_get/put() issue if the node has not been retained before that. Instead of passing the root node, pass NULL, which does exactly the same: iterate over all DT nodes, starting from the root node.
