If a serial-tegra interface does not have an alias, the driver fails to
probe with an error:
serial-tegra 70006300.serial: failed to get alias id, errno -19
This prevents the bluetooth device from being accessible.

Huh... seems a bit over the top to fail in the absence of an alias. Oh
well.

Applied, thanks.
