commit 78857614104a26cdada4c53eea104752042bf5a1 upstream. The GENERIC_PCI_IOMAP does not depend on CONFIG_PCI so move it to the CONFIG_MIPS symbol so it's always selected for MIPS. This fixes the missing pci_iomap declaration for MIPS. Moreover, the pci_iounmap function was not defined in the io.h header file if the CONFIG_PCI symbol is not set, but it should since MIPS is not using CONFIG_GENERIC_IOMAP. This fixes the following problem on a allyesconfig: drivers/net/ethernet/3com/3c59x.c:1031:2: error: implicit declaration of function 'pci_iomap' [-Werror=implicit-function-declaration] drivers/net/ethernet/3com/3c59x.c:1044:3: error: implicit declaration of function 'pci_iounmap' [-Werror=implicit-function-declaration] Signed-off-by: Markos Chandras <markos.chandras@xxxxxxxxxx> Acked-by: Steven J.
