usb: usb_generic_probe() obeys authorization
If called and the device is not authorized to be used, then we won't choose a configuration (as they are not a concept that exists for an unauthorized device). However, the device is added to the system. Signed-off-by: Inaky Perez-Gonzalez <inaky@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
