Lets make changes accordingly. v2: Fix checkpatch warnings. (Ankit) v3: Add separate functions for computing expected secondary_big/ultrajoiner pipes. (Ankit) v4: -Streamline the helpers for ultrajoiner. (Ville) -Add fixup to accommodate PIPED check for ultrajoiner. (Ville) -Add more Ultrajoiner drm_WARNs. (Ville) v5: Remove spurious newline.
