So that is commit f6308b36c411dc5 "ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs"? This seems to have been selected for -stable as well so the problem will be spreading as distros start pushing stable kernel updates :-( That came in through the ACPI tree, Rafael do you want to revert it if there is no better quickfix? This adds an interesting twist to the general statement that new PCI/ACPI IDs should go into stable BTW, maybe they should not always do that.
