USB uses the .find_bridge() callback from struct acpi_bus_type incorrectly, because as a result of the way it is used by USB every device in the system that doesn't have a bus type or parent is passed to usb_acpi_find_device() for inspection. What USB actually needs, though, is to call usb_acpi_find_device() for USB ports that don't have a bus type defined, but have usb_port_device_type as their device type, as well as for USB devices. To fix that replace the struct bus_type pointer in struct acpi_bus_type used for matching devices to specific subsystems with a .match() callback to be used for this purpose and update the users of struct acpi_bus_type, including USB, accordingly. Define the .match() callback routine for USB, usb_acpi_bus_match(), in such a way that it will cover both USB devices and USB ports and remove the now redundant .find_bridge() callback pointer from usb_acpi_bus.
