I renamed *spi_i2c_slave* to *serial_bus_slave* to reflect this.

This needs Johan Hovold's "serdev: fix registration of second slave" pat=

ch.

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?

OK

Please feel free to add

Acked-by: Rafael J. Wysocki <redacted>

to the ACPI core change.

And I will assume that this series will go in via the tty tree.

Thanks,
Rafael
