Don't worry. The patch he acked has already been dimissed...

They are currently disussing an overengineered version that allows to chain USB-UARTs...
And again the line disciplines come up.
I have looked into them a little:
and yes, they don't look that bad. It seems to be possible to get notified about open()/close()
and data if I understand properly.
But what I don't understand is how to register a line discipline... For a driver that only knows
(from DT) to which UART it is connected to.
Anyways we can lean back now and wait until their discussion settles. Then there are two outcomes:
a) we can adapt our drivers to use what they give us -> they can not reject any more
b) we still can't -> then we can resubmit our stuff, which forces them to either update their solution until we can or accept ours
So we are in a better situation now.
