Mathias Nyman a44c6c61af usb: port: Don't try to peer unused USB ports based on location ... commit 69c63350e573367f9c8594162288cffa8a26d0d1 upstream. Unused USB ports may have bogus location data in ACPI PLD tables. This causes port peering failures as these unused USB2 and USB3 ports location may match. Due to these failures the driver prints a "usb: port power management may be unreliable" warning, and unnecessarily blocks port power off during runtime suspend. This was debugged on a couple DELL systems where the unused ports all returned zeroes in their location data. Similar bugreports exist for other systems. Don't try to peer or match ports that have connect type set to USB_PORT_NOT_USED.
