Make sure to use the current alternate setting when looking up the
endpoints on epic devices to avoid binding to an invalid interface.
Failing to do so could cause the driver to misbehave or trigger a WARN()
in usb_submit_urb() that kernels with panic_on_warn set would choke on.

This device presents itself as a USB hub with three attached devices: - An ACM serial port connected to the GPS module (not affected by this commit) - An FTDI serial port connected to the GPS module (1546:0502) - Another FTDI serial port connected to the ODIN-W2 radio module (1546:0503) This commit registers U-Blox's VID and the PIDs of the second and third devices.

These are the Foxconn-branded variants of the Dell DW5821e modules, same USB layout as those. The device exposes AT, NMEA and DIAG ports in both USB configurations.

Drop the redundant port open flag and corresponding checks. USB serial core will not call any of these driver callbacks for a closed port, and the write URBs are stopped at close(). Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Johan Hovold <johan@kernel.org>
