[PATCH] mem driver: fix conditional on isa i/o support
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' Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Acked-by: Linas Vepstas <lins@austin.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
