Subject: [PATCH] of: unittest: Fix np reference leak in of_unittest_bus_3cell_ranges()
Date: Thu, 17 Sep 2026 12:46:53 +0000 [thread overview]
Message-ID: <20260917124653.2151894-1-vulab@iscas.ac.cn> (raw)
of_range_parser_init() can fail when the node lacks a ranges property.
That error path returns without dropping the reference taken by
of_find_node_by_path(). Add the missing of_node_put().
Fixes: 3d5089c4263d ("of/address: Add support for 3 address cell bus")
