The purpose of this patch series is to upgrade power management in xxxxxxxx drivers. This has been done by upgrading .suspend() and .resume() callbacks. The upgrade makes sure that the involvement of PCI Core does not change the order of operations executed in a driver. Thus, does not change its behavior. In general, drivers with legacy PM, .suspend() and .resume() make use of PCI helper functions like pci_enable/disable_device_mem(), pci_set_power_state(), pci_save/restore_state(), pci_enable/disable_device(), etc. to complete their job. The conversion requires the removal of those function calls, change the callbacks' definition accordingly and make use of dev_pm_ops structure. All patches are compile-tested only.
