[PATCH] drm/meson: Fix remote device node leak in meson_encoder_dsi_probe()
From: Wentao Liang <hidden>

The device node returned by of_graph_get_remote_node() is never
released. of_drm_find_and_get_bridge() only uses it as a lookup key and
takes its own reference on the bridge, so drop the node reference once
the lookup is done, as meson_encoder_cvbs_probe() already does.
