The pci_pm_thaw() routine is similar to pci_pm_resume(), but it runs the device driver's pm->thaw() callback instead of pm->resume(). It is executed asynchronously for different PCI devices that don't depend on each other in a known way. -The complete phase it the same as for system resume. +The complete phase is the same as for system resume.
