Summary
PM / devfreq: exynos-ppmu: Fix refcount leak in of_get_devfreq_events
Details

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

PM / devfreq: exynos-ppmu: Fix refcount leak in ofgetdevfreq_events

ofgetchildbyname() returns a node pointer with refcount incremented, we should use ofnodeput() on it when done. This function only calls ofnodeput() in normal path, missing it in error paths. Add missing ofnodeput() to avoid refcount leak.
