| Subject: hexagon: add memset_io() helper |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| [ 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] |
