[PATCH 032/142] usb: usb_probe_interface() obeys authorization

Greg Kroah-Hartman <[email protected]>
Newsgroups gmane.linux.usb.devel
Message-ID <[email protected]>
From: Inaky Perez-Gonzalez <[email protected]>

If called and the device is not authorized to be used, it won't
configure the interface and print a message saying so.
