[PATCH net-next #2 30/39] dl2k: stop using net_device.{base_addr, irq} and convert to __iomem.

[Francois Romieu <romieu@fr.zoreil.com>]

The eeprom registers always use the same PCI bar whereas the general
registers may either use the same mapping as the eeprom registers or
a different one. It is thus possible to simplify parse_eeprom().
