If it can't return NULL, why bother having a return value at all?
And this is not the only place where get_device() is checked for a NULL
return value.
We _really_ need to come up with a consistent view here.
If get_device() can never return NULL I would strongly argue for making
it a void function.
If it _can_ return NULL we need to check for it.
Either way I don't mind; but please stay consistent.
Cheers,
Hannes
