Title
power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe
Summary
In the Linux kernel, the following vulnerability has been resolved:
power/reset: arm-versatile: Fix refcount leak in versatile_reboot_probe
of_find_matching_node_and_match() 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.
