Hi Greg,
I could change the commit message to:

---------
serial: sc16is7xx: add missing support for rs485 devicetree properties

Retrieve rs485 devicetree properties on registration of sc16is7xx ports
in case they are attached to an rs485 transceiver.
---------

I don't think that it should be considered as a bug fix, but maybe as a
missing feature.

And does it mean that it should also go to older (stable) kernels then?
If yes, then do I need to add the "Fixes" tag?

Thank you,
Hugo.
