Title
ARM: meson: Fix refcount leak in meson_smp_prepare_cpus
Summary
In the Linux kernel, the following vulnerability has been resolved: ARM: meson: Fix refcount leak in meson_smp_prepare_cpus 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.
