Subject: [PATCH] arm: npcm: Fix some refcount leaks
Date: Thu, 12 May 2022 07:03:34 +0400 [thread overview]
Message-ID: <20220512030334.52918-1-linmq006@gmail.com> (raw)
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: 7bffa14c9aed ("arm: npcm: add basic support for Nuvoton BMCs")
