Subject: [PATCH] of: overlay: Fix missing of_node_put() in error case of init_overlay_changeset()
Date: Fri, 2 Jun 2023 11:05:02 +0900 [thread overview]
Message-ID: <20230602020502.11693-1-hayashi.kunihiko@socionext.com> (raw)
In init_overlay_changeset(), the variable "node" is from
of_get_child_by_name(), and the "node" should be discarded in error case.
Fixes: d1651b03c2df ("of: overlay: add overlay symbols to live device tree")
