When CONFIG_PCI is not enabled, CONFIG_EISA=y, and CONFIG_GENERIC_IOMAP=y, drivers/net/3c59x.c build fails due to a recent small change to <asm-generic/iomap.h> that surrounds pci_iomap() and pci_iounmap() with #ifdef CONFIG_PCI/#endif. Since that patch to iomap.h looks correct, add stubs for pci_iomap() and pci_iounmap() with CONFIG_PCI is not enabled to fix the build errors. drivers/net/3c59x.c:1026: error: implicit declaration of function 'pci_iomap' drivers/net/3c59x.c:1038: error: implicit declaration of function 'pci_iounmap' Signed-off-by: Randy Dunlap <rdunlap@xenotime.net> Cc: Jonas Bonn <jonas@southpole.se> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
