[PATCH] remove usb_suspend_device() parameter
This patch removes the extra usb_suspend_device() parameter. The original
reason to pass that parameter was so that this routine could suspend any
active children. A previous patch removed that functionality ... leaving
no reason to pass the parameter. A close analogy is pci_set_power_state,
which doesn't need a pm_message_t either.
On the internal code path that comes through the driver model, the parameter
is now used to distinguish cases where USB devices need to "freeze" but not
suspend. It also checks for an error case that's accessible through sysfs:
attempting to suspend a device before its interfaces (or for hubs, ports).
