Subject: [PATCH v2] soc: tegra: fuse: Add missing of_node_put in tegra_init_fuse
Date: Thu, 16 Jun 2022 09:46:36 +0800 [thread overview]
Message-ID: <20220616014636.3972830-1-windhl@126.com> (raw)
In this function, of_find_matching_node() will return a node
pointer with refcount incremented. We should use of_node_put
when the pointer *np* is not used anymore.
