It looks like you didn't compile your driver after rebasing.

The first error here is pretty trivial (missing drm_bridge.h include),
but the second one is there becaus the DP link helpers you rely on
have been removed.

Can you send a patch to fix this? Otherwise, we can just revert the
offending patch.
