[PATCH 1/3] can: gs_usb: gs_usb_get_timestamp(): fix endpoint parameter for usb_control_msg_recv()

[Marc Kleine-Budde <mkl@pengutronix.de>]

The 2nd argument of usb_control_msg_recv() is the "endpoint",
usb_control_msg_recv() will internally convert the endpoint into a
pipe with usb_rcvctrlpipe().

In gs_usb_get_timestamp() not the endpoint "0" is passed, but the
pipe. This worked by accident as endpoint is a __u8 and the lowest 8
bits of the pipe are 0. Fix this copy/paste error by using the correct
endpoint of "0".
