| |
This change corrects the logic on the preprocessor conditionals that include support for ISA port i/o (/dev/ioports) into the mem character driver.
This fixes the following error when building for powerpc platforms with CONFIG_PCI=n.
drivers/built-in.o: undefined reference to `pci_io_base'

I've only tested this on powerpc (cell) build. Testing on other arch's would be welcome.
