From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> This is still work-in-progress on the issue of PNP0A03 _CRS methods that are buggy or not interpreted correctly by Linux. The previous try at: https://lore.kernel.org/r/20220304035110.988712-1-helgaas@xxxxxxxxxx caused regressions on some Chromebooks: https://lore.kernel.org/r/Yjyv03JsetIsTJxN@xxxxxxxxxxxxx This v2 drops the commit that caused the Chromebook regression, so it also doesn't fix the issue we were *trying* to fix on Lenovo Yoga and Clevo Barebones. The point of this v2 update is to split the logging patch into (1) a pure logging addition and (2) the change to only clip PCI windows, which was previously hidden inside the logging patch and not well documented.
