IMHO &pdev->dev is neater and saves an extra line. I would agree if this
would be something like &foo->bar->baz->dev but it is not.

Anyway, no feelings about this so feel free to add,

I have no strong opinion, but one thing which may play in favour of
the patches is that all other drivers, that have their custom
->probe() implemented, are using temporary variable. That said, let's
consider this as unification among Intel pin control drivers.
