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.
Still, I would go ahead and find out if there is any scenario where pdev can go wrong during device registration. Thanks.
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.
