[PATCH 3/3] sparc: prom: Fix reference leak in of_console_init

From: Miaoqian Lin
Date: Mon Jun 06 2022 - 23:34:31 EST


of_find_node_by_path() returns a node pointer with
refcount incremented, we should use of_node_put() on it when not need
anymore.
Add missing of_node_put() to avoid refcount leak.

Fixes: c73fcc846c91 ("[SPARC]: Fix serial console device detection.")
