PM / devfreq: event: Call of_node_put() only once in devfreq_event_get_edev_by_phandle()
An of_node_put(node) call was immediately used after a null pointer check
for the local variable “edev” at the end of this function implementation.
Thus call such a function only once instead directly before the check.
This issue was transformed by using the Coccinelle software.
