drm_vma_offset_remove — Remove offset node from manager
| void drm_vma_offset_remove ( | struct drm_vma_offset_manager * mgr, | 
| struct drm_vma_offset_node * node ); | 
   Remove a node from the offset manager. If the node wasn't added before, this
   does nothing. After this call returns, the offset and size will be 0 until a
   new offset is allocated via drm_vma_offset_add again. Helper functions like
   drm_vma_node_start and drm_vma_node_offset_addr will return 0 if no
   offset is allocated.
