Subject: [PATCH 1/2] drm/meson: encoder_cvbs: Fix refcount leak in meson_encoder_cvbs_init
Date: Tue, 31 May 2022 18:48:15 +0400 [thread overview]
Message-ID: <20220531144818.26943-1-linmq006@gmail.com> (raw)
of_graph_get_remote_node() returns remote device nodepointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: 318ba02cd8a8 ("drm/meson: encoder_cvbs: switch to bridge with ATTACH_NO_CONNECTOR")
