Of course, I was not paying enough attention here, sorry about that. Thanks, Miquèl

It is quite uncommon to use a driver helper with parameters like *pdev and __iomem *base. It is much cleaner and close to today's standards to provide the per-device driver structure and then access its internals. Let's do this with at91_resete_status() before making more modifications to this helper.
