From e25a6946d8eb5d84a2f70c91605181ea71b79966 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Fri, 23 Apr 2021 17:09:28 +0200 Subject: [PATCH] openrisc: Fix a memory leak [ 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.
