Subject: [PATCH] mtd: partitions: Fix refcount leak in parse_redboot_of
Date: Thu, 26 May 2022 15:06:49 +0400 [thread overview]
Message-ID: <20220526110652.64849-1-linmq006@gmail.com> (raw)
of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: 237960880960 ("mtd: partitions: redboot: seek fis-index-block in the right node")
