This
The cs89x0 driver can either be built as an ISA driver or a platform driver, the choice is controlled by the CS89x0_PLATFORM Kconfig symbol. Building the ISA driver on a system that does not have a way to map I/O ports fails with this error: drivers/built-in.o: In function `cs89x0_ioport_probe.constprop.1': :(.init.text+0x4794): undefined reference to `ioport_map' :(.init.text+0x4830): undefined reference to `ioport_unmap' This changes the Kconfig logic to take that option away and always force building the platform variant of this driver if CONFIG_HAS_IOPORT_MAP is not set. This is the only correct choice in this case, and it avoids the build error.
