[ Upstream commit a57ab96ef9dde231d4d46edba4d5f73720edc16a ]
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]
