[PATCH] drm: logicvc: Add missing of_node_put() in logicvc_drm_config_parse()

From: Peng Wu
Date: Tue Jun 14 2022 - 02:30:52 EST


of_get_child_by_name() 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.
