Patchset:
PS4: This is confusing. Did once more somebody invent something new without updating the existing code? It looks to me that this only doesn't add conflicting SSDT entries because a weak function isn't implemented (intel_igd_get_controller_info()), or devicetree settings aren't filled. Both is hard to notice, which makes the overall code hard to follow. It would be much better, IMO, to drop the legacy code alltogether.
I would prefer that existing code gets updated to use the generic driver instead of adding even more redundant paths.
