Subject: [PATCH] mtd: parsers: ofpart: Fix refcount leak in bcm4908_partitions_fw_offset
Date: Sun,  5 Jun 2022 11:07:23 +0400	[thread overview]
Message-ID: <20220605070726.5979-1-linmq006@gmail.com> (raw)

of_find_node_by_path() 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: bb17230c61a6 ("mtd: parsers: ofpart: support BCM4908 fixed partitions")
