Description
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.
