[PATCH 55/59] drm/ttm: drop type manager has_type

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dave Airlie <airlied@xxxxxxxxxx>

under driver control, this flag isn't needed anymore,
remove the API that used to access it, and consoldiate
with the used api.
