From: Shuah Khan shuahkh@osg.samsung.com
commit e1346fd87c71a1f61de1fe476ec8df1425ac931c upstream.
usbip_dump_usb_device() and usbip_dump_urb() print kernel addresses. Remove kernel addresses from usb device and urb debug msgs and improve the message content.
Instead of printing parent device and bus addresses, print parent device and bus names.
