[PATCH] drm/meson: Fix reference count leak in meson_encoder_dsi_probe
From: Miaoqian Lin <hidden>
Date: 2025-10-27 08:43:15
Also in:
dri-devel, linux-amlogic, lkml, stable
Subsystem:

The of_graph_get_remote_node() function returns a device node with its
reference count incremented. The caller is responsible for calling
of_node_put() to release this reference when done.
