Add a header file for ttm_range_manager function prototypes to eliminate build errors: ../drivers/gpu/drm/vmwgfx/vmwgfx_drv.c: In function ‘vmw_vram_manager_init’: ../drivers/gpu/drm/vmwgfx/vmwgfx_drv.c:678:8: error: implicit declaration of function ‘ttm_range_man_init’; did you mean ‘ttm_tt_mgr_init’? [-Werror=implicit-function-declaration] ret = ttm_range_man_init(&dev_priv->bdev, TTM_PL_VRAM, false, ../drivers/gpu/drm/vmwgfx/vmwgfx_drv.c: In function ‘vmw_vram_manager_fini’: ../drivers/gpu/drm/vmwgfx/vmwgfx_drv.c:690:2: error: implicit declaration of function ‘ttm_range_man_fini’; did you mean ‘ttm_pool_mgr_fini’? [-Werror=implicit-function-declaration] ttm_range_man_fini(&dev_priv->bdev, TTM_PL_VRAM); Fixes: 9c3006a4cc1b ("drm/ttm: remove available_caching") Fixes: a343160235f5 ("drm/vmwgfx/ttm: fix the non-THP cleanup path.")
