| Subject: openrisc: Fix a memory leak |
| |
| From: Christophe JAILLET <christophe.jaillet@wanadoo.fr> |
| |
| [ 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. |
| |
| Fixes: 9d02a4283e9c ("OpenRISC: Boot code") |
