Yes, everything is fine. And just before I left my desk yesterday, Ì think I was able to figure this out myself: When poking around in /sys/class/tty/ttyS8 I found the type was 0. However, in my code I set it to PORT_16550. I learned I have to set the UPF_FIXED_TYPE flag. This solved the issue - but many thanks! I sent the driver yesterday, but I will resend it. It has some whitespace issues.
