USB: OHCI: host-controller resumes leave root hub suspended
Drivers in the ohci-hcd family should perform certain tasks whenever their controller device is resumed. These include checking for loss of power during suspend, turning on port power, and enabling interrupt requests. Until now these jobs have been carried out when the root hub is resumed, not when the controller is. Many drivers work around the resulting awkwardness by automatically resuming their root hub whenever the controller is resumed. But this is wasteful and unnecessary. To simplify the situation, this patch (as1066) adds a new core routine, ohci_finish_controller_resume(), which can be used by all the OHCI-variant drivers. They can call the new routine instead of resuming their root hubs. And ohci-pci.c can call it instead of using its own special-purpose handler.
