From: Kunihiko Hayashi <hayashi.kunihiko@xxxxxxxxxxxxx>
[ Upstream commit 39affd1fdf65983904fafc07cf607cff737eaf30 ]
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")
