From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> [ Upstream commit c019d92457826bb7b2091c86f36adb5de08405f9 ] 'setup_find_cpu_node()' take a reference on the node it returns. This reference must be decremented when not needed anymore, or there will be a leak. Add the missing 'of_node_put(cpu)'. Note that 'setup_cpuinfo()' that also calls this function already has a correct 'of_node_put(cpu)' at its end.
