From: Ville Syrjälä <[email protected]> With the cdclk state, all the .modeset_commit_cdclk() hooks are now pointless wrappers. Let's replace them with just a .set_cdclk() function pointer. However let's wrap that in a small helper that does the state comparison and prints a unified debug message across all platforms. We didn't even have the debug print on all platforms previously. This reduces the clutter in intel_atomic_commit_tail() a little bit.
