of course not. You can have devices that just play well with default 
values or devices where you don't need the flexibility of platform data. 
That's why we check.

platform_device pointers on the other hand, are guaranteed to be always 
true, if it isn't then you should oops, you deserve to oops because 
something is really really wrong.

if that scenario ever happens, it's either a bug on your implementation 
or driver-core. In both cases you deserve to oops so we catch such 
problems at early stages.
