In theory this series could go in through the acpi-tree without my
fix. It would only affect an error case where an unlikely failure to
register an ACPI serdev device, would prevent the tty-class device from
being registered instead of the controller. That is, something we can
live with until this all converges in 4.15-rc1 if needed.

That said, I think we should consider taking all serdev changes, and
therefore also the ACPI patch, through the tty tree instead in order to
avoid merge conflicts. Rafael?
