+Subject: [PATCH] drm/panel: kingdisplay-kd097d04: Disable EoTp
+
+Since commit d97e71e44937 ("drm/bridge: synopsys: dw-mipi-dsi: enable EoTp by
+default") panel output on an Acer Chromebook Tab 10 (google-dru) is corrupted.
+The tablet I use is equipped with a kingdisplay-kd097d04 panel, disabling EoTp
+restores the correct functionality.
+
+Fixes: d97e71e44937 ("drm/bridge: synopsys: dw-mipi-dsi: enable EoTp by default")
+Signed-off-by: Sebastian Fleer <dev@dwurp.de>
