Sounds good.

BlueZ 4 API guarantees the property will be present, and therefore
device->alias should always be set. The obvious exception is BlueZ
misbehaving, but this condition might hold true for device->name as
well, which we're not checking either.
I don't think there's any other scenario where the alias could be NULL
and the name be set outside bluetooth-util.
So while your point is valid, I suggest we fix this in a later patch,
in a similar way that the BlueZ 5 patchset does (set device_info_valid
to -1 if any non-optional property is missing).
Cheers,
Mikel
