In the Linux kernel, the following vulnerability has been resolved:

video: fbdev: clcdfb: Fix refcount leak in clcdfb_of_vram_setup

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.
