Subject: [PATCH] usb: gadget: lpc32xx_udc: Fix refcount leak in lpc32xx_udc_probe
Git-commit: 4757c9ade34178b351580133771f510b5ffcf9c8
Patch-mainline: v5.19-rc3
References: git-fixes
of_parse_phandle() 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.
of_node_put() will check NULL pointer.
