The loop iterates through all phandles but\nnever releases the reference, causing a refcount leak on each iteration.\n\nAdd of_node_put() calls to release the reference after extracting the\nneeded arguments and on the error path when devm_kzalloc() fails.\n\nThis bug was detected by our static analysis tool and verified by my\ncode review."
