From a52972ee706b438302eb0350e61f378eb191e3d1 Mon Sep 17 00:00:00 2001 From: Liang He Date: Fri, 17 Jun 2022 19:53:23 +0800 Subject: [PATCH] xtensa: xtfpga: Fix refcount leak bug in setup 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.
