Subject: [PATCH 26/30] usb: gadget: function: u_serial: Repair misdocumented function argument

Looks as though this has been an issue since the driver's
inception back in 2014.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/gadget/function/u_serial.c:538: warning: Function parameter or member 'port' not described in 'gs_start_io'
 drivers/usb/gadget/function/u_serial.c:538: warning: Excess function parameter 'dev' description in 'gs_start_io'
