Thanks for the heads-up. There's no technical conflict but the build fails.
I'll fix it for v3 after I get the de-midlayering of drm_bridge done
(see https://patchwork.freedesktop.org/patch/343643/?series=70432&rev=1 for
context) and the s/bridge->dev/bridge->drm/ patch merged
(https://patchwork.freedesktop.org/patch/343824/).
