[PATCH] serial: do not add port that is not initialized
if the port is not initialized with correct iobase, and membase, we don't
need to add that port.
for x86, when pnpacpi is enabled, we will not get extra ttyS1/ttyS2/ttyS3 in
/sys/devices/platform/serial8250/tty

What if someone wants to run setserial on /dev/ttyS1 to set it's base
address, irq and other parameters? People still do this.
I agree that people still use setserial that way, and we shouldn't
make this change because it would break things.
But I also agree with Yinghai that these extra phantom devices are
just weird. It would be a lot nicer if there were a way to say,
"please, Mr. Serial Driver, create me a new ttyS device with these
parameters."
But no, I'm not volunteering to do that.
Indeed, and since distros still haven't picked up my setserial v3,
I see little chance of that ever being practical. Not that I've
really tried very hard to get them to - no real idea who to contact
to make that happen, and of course I've no interest in making it
happen anymore.
so remove these extra phantom devices, the kernel distros will use your setserial v3.
we can put some comments in code, so later they will find clue about your setserial v3.
