[PATCH] serial: don't announce CIR serial ports

From: Maciej S. Szmigiero
Date: Sun Aug 02 2015 - 17:10:46 EST


CIR type serial ports aren't real serial ports.
This is just a way to prevent legacy serial driver
from probing and eventually binding some resources
so don't announce them like normal serial ports.
