Serial Synth Workaround

[Rob]

I understood that you had to comment out this statement in drivers/staging/speakup/serialio.c:
  if (err) {
   pr_warn("Unable to allocate port at %x, errno %i",
    ser->port, err);
   return NULL;
}
Was that wrong? Because I got a bunch of errors from make.
I tried commenting out just the
   return NULL;
part and still got errors. It is plainly obvious that I am no coder. Lol. What needs commenting out, exactly?
