This is a PCI driver. Why not using the pcim_enable_device() with the
respective pcim_*() call for the IO region?

I believe the driver misses pci_disable_device() as of the current
implementation, switching to pcim_*() should address that as well.

(Somewhere here I would expect pci_disable_device() to be called.)
