Ugh.
So, patch 1/24 needs to be amended with this
diff --git a/drivers/gpu/drm/rockchip/rockchip_lvds.c b/drivers/gpu/drm/rockchip/rockchip_lvds.c
index e67f4ea28c0e..3f33034b3f58 100644
--- a/drivers/gpu/drm/rockchip/rockchip_lvds.c
+++ b/drivers/gpu/drm/rockchip/rockchip_lvds.c
@@ -377,8 +377,10 @@ static int rockchip_lvds_bind(struct device *dev, struct device *master,
}

and patch 22/24 with this

But that is of course just a stop-gap. The real fix is to adapt to the
"drm: bridge: Add support for static image formats" series from Jacopo.
But that's orthogonal.
Cheers,
Peter
