I think you should remove "CK Hu <ck.hu@mediatek.com>" and add latest
mediatek drm maintainer:

DRM DRIVERS FOR MEDIATEK
M:	Chun-Kuang Hu <chunkuang.hu@kernel.org>
M:	Philipp Zabel <p.zabel@pengutronix.de>
L:	dri-devel@lists.freedesktop.org
S:	Supported
F:	Documentation/devicetree/bindings/display/mediatek/
F:	drivers/gpu/drm/mediatek/

CK
