When the PCI devres API was introduced to this driver, it was wrongly assumed that initializing the device with pcim_enable_device() instead of pci_enable_device() will make all PCI functions managed. This is wrong and was caused by the quite confusing PCI devres API in which some, but not all, functions become managed that way. The function pci_iomap_range() is never managed. Replace pci_iomap_range() with the actually managed function pcim_iomap_range().
