USB: serial: metro-usb: dummy implement write_int_callback() function.
This function is never called now. Because we don`t send much data to the device, only one byte via usb_interrupt_msg(). That doesn't require callback function. But without declaration of write_int_callback inside the struct usb_serial_driver, the usb_serial_probe doesn't initialize endpoint address for the interrupt out pipe(interrupt_out_endpointAddress). This endpoint is necessary for sending data via usb_interrupt_msg() function. Signed-off-by: Aleksey Babahin <tamerlan311@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
