The currently used 'extern inline' directive causes the following compiler warnings if CONFIG_SWAP_IO_SPACE is defined:

However those errors are already present if the 'arch/mips/include/asm/io.h' file is checked with checkpatch.pl. The cleanup should be done in a separare patch. --- arch/mips/include/asm/io.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
