None of the acquired node\nreferences (np, intermediate parent, np_pmic_parent) are ever released\nvia of_node_put(), causing a reference leak on every loop iteration.\n\nAdditionally, of_find_node_by_name() can return NULL, but the result was\nimmediately passed to of_node_full_name() and of_get_parent() without a\nNULL check, which could lead to a NULL pointer dereference.\n\nFix this by:\n- Adding a NULL check for np after of_find_node_by_name()\n- Storing the intermediate parent node in a local variable np_parent\n- Calling of_node_put() on np, np_parent and np_pmic_parent at the\n  end of each loop iteration","state":0,"publishedAt":"2026-09-24T15:52:15.213+00:00","modifiedAt":"2026-10-19T09:08:27.727+00:00","affected":[{"ecosystem":"Vendor
