Subject: drm/meson: Fix refcount leak in meson_encoder_hdmi_init
From: Miaoqian Lin <linmq006@xxxxxxxxx>
commit 7381076809586528e2a812a709e2758916318a99 upstream.
of_find_device_by_node() takes reference, we should use put_device()
to release it when not need anymore.
Add missing put_device() in error path to avoid refcount
leak.
