xen-platform: Convert to generic power management (77b84bb3) · Commits · 戴 / test

Convert xen-platform from the legacy PCI power management callbacks to the generic operations. This is one step towards removing support for the legacy PCI callbacks. The generic .resume_noirq() operation is called by pci_pm_resume_noirq() at the same point the legacy PCI .resume_early() callback was, so this patch should not change the xen-platform behavior.
