> 
> The devargs of a device can be replaced by a newly allocated one
> when trying to probe again the same device (multi-process or
> multi-ports scenarios). This is breaking some pointer references.
> 
> It can be avoided by copying the new content, freeing the new devargs,
> and returning the already inserted pointer.
