USB: qcserial: support generic Qualcomm serial ports
No need to verify the interface layout when doing interface number based matching. We can safely trust the device ID table in this case. This allows the driver to support any USB interface layout for non-Gobi 1k/2k+ devices. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
