CVE-2022-49668: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: PM / devfreq: exynos-ppmu: Fix refcount leak in of_get_devfreq_events of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. This function only calls of_node_put() in normal path, missing it in error paths. Add missing of_node_put() to avoid refcount leak.
