Subject: Serial.c Bug

I have found a bug. It is in support of serial cards which uses
memory for
I/O insted of ports. I made a patch for serial.c and fix one place, but
probably the problem like this one could be somewhere else.

If you try to use setserial with such cards you will get "Address in use"
(-EADDRINUSE)

Best regards,
