Yes but no. The result is the same however: the compiler assumes that the 
pointer is not NULL.

For a proper fix, we would need to stop mixing vlc_object_t proper and 
vlc_object_t containers like they are the same thing. (Compare 'struct device' 
in the kernel.)

That said, in this case, you could probably either ensure that the object is 
always a vlc_object, or simply cast - to avoid the ternary.
