2018-11-05drm/ttm: Provide ttm_bo_global_{init/release}() for struct ttm_bo_globalThomas Zimmermann2-21/+48
So far, struct ttm_bo_global_ref was the only way of initializing a struct ttm_bo_global. Providing separate initializer and release functions for struct ttm_bo_global gives drivers the option of implementing their own init and release callbacks for drm_global_references of type DRM_GLOBAL_TTM_BO. The original functions for initializing and releasing via struct ttm_bo_global_ref are wrappers around the new interfaces.
