[PATCH v2] drm/ttm: fixup ttm_bo_add_move_fence

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

 



It looks like we still need to call dma_fence_put() on the man->move,
otherwise we just end up leaking it, leading to fireworks later.

v2(Daniel):
  - Simplify the function tail

Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5689
