+Subject: Revert "drm/mipi-dsi: Set the fwnode for mipi_dsi_device"
+To: stable@vger.kernel.org, Saravana Kannan <saravanak@google.com>,  Greg KH <gregkh@linuxfoundation.org>
+Cc: Seiya Wang <seiya.wang@mediatek.com>,  "Jason-JH.Lin" <jason-jh.lin@mediatek.com>,  Singo Chang <singo.chang@mediatek.com>

+
+This reverts commit 139c27648f8d3b2283f74715d8e7f0df7f5e55ca which is
+commit a26cc2934331b57b5a7164bff344f0a2ec245fc0 upstream.
+
+Reason for revert:
+1. The commit [1] does not land on linux-5.15, so this patch does not
+fix anything.
+
+2. Since the fw_devlink improvements series [2] does not land on
+linux-5.15, using device_set_fwnode() causes the panel to flash during
+bootup.
+
+Incorrect link management may lead to incorrect device initialization,
+affecting firmware node links and consumer relationships.
+The fwnode setting of panel to the DSI device would cause a DSI
+initialization error without series[2], so this patch was reverted to
+avoid using the incomplete fw_devlink functionality.
