Hi All, As explained in the changelog of patch [2/5], using struct pci_platform_pm_ops for ACPI is not particularly beneficial, so it is better to get rid of it and call the functions pointed to by it directly from the PCI core. However, struct pci_platform_pm_ops is also used by the Intel MID support code that basically is regarded as dead which is why the majority of it has been dropped already as of commit 4590d98f5a4f ("sfi: Remove framework for deprecated firmware"). Since it doesn't make much sense to update that code, patch [1/5] drops the PCI part of it along with some arch pieces that are only needed for the PCI stuff. The main modification is made by patch [2/5] (see the changelog thereof for details). The rest is just cleanups and some code consolidation on top of that. Thanks!
