I could have created a temporary buffer within the function and have 
passed it to __dev_alloc_name but this is exactly what does 
'dev_alloc_name'.
So 'dev_alloc_name' replaces '__dev_alloc_name' but takes a 'dev' 
parameter which is not passed to 'dev_get_valid_name'.
Instead of passing an extra parameter 'dev', I just replaced the 'net' 
parameter by the 'dev' parameter and extracted the 'net' pointer from it.

I have a few patches cleaning up these functions and the callers but I 
prefer to send them against net-next-2.6.
