| Subject: xtensa: xtfpga: Fix refcount leak bug in setup |
| |
| From: Liang He <windhl@126.com> |
| |
| commit 173940b3ae40114d4179c251a98ee039dc9cd5b3 upstream. |
| |
| In machine_setup(), of_find_compatible_node() will return a node |
| pointer with refcount incremented. We should use of_node_put() when |
| it is not used anymore. |
