We already have memcpy_toio(), but not memset_io(), so let's add the obvious version to allow building an allmodconfig kernel without errors like drivers/gpu/drm/ttm/ttm_bo_util.c: In function 'ttm_bo_move_memcpy': drivers/gpu/drm/ttm/ttm_bo_util.c:390:3: error: implicit declaration of function 'memset_io' [-Werror=implicit-function-declaration] Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- arch/hexagon/include/asm/io.h | 6 ++++++ 1 file changed, 6 insertions(+) -- 2.9.0
