Subject: [PATCH] usb: improve "not suspended yet" message in hub_suspend()
Reading through a recent bug report [1], Alan notes:
"Dan, the warning message in hub_suspend() should mention that the
child device isn't suspended yet."
...update the warning from:
"usb usb3-port4: not suspended yet"
...to:
"usb usb3-port4: device 3-4: not suspended yet"
