This will prevent error message that pop up when the serial
port is not present
---
This seems quite hacky to me, but we have an issue where if we remove
a serial port from the device tree the serial port won't work.
It seems link it's still in /dev/ttySN but it's not configured properly.
I looked for udev rules and items in /proc and /sys to try to use but
I did not see anything...
Is there a better approach than this?
