Subject: [PATCH] of: unittest: Fix np reference leak in of_unittest_printf()
Date: Thu, 17 Sep 2026 13:08:10 +0000 [thread overview]
Message-ID: <20260917130810.2152851-1-vulab@iscas.ac.cn> (raw)
of_find_node_by_path() returns a node with an elevated reference count,
but the function returns without ever dropping it. Add the missing
of_node_put() so the reference is not leaked.
Fixes: ce4fecf1fe15 ("vsprintf: Add %p extension "%pOF" for device tree")
