Subject: ARM: cns3xxx: Fix refcount leak in cns3xxx_init
X-Git-Tag: v6.1-rc5~983^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ba904b6b16e08de5aed7c1349838d9cd0d178c5;p=platform%2Fkernel%2Flinux-starfive.git

ARM: cns3xxx: Fix refcount leak in cns3xxx_init

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.
