[PATCH 5/8] drm/vmwgfx: partially revert "Adapt validation code for reference-free lookups"

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

 



This reverts commit 64ad2abfe9a628ce79859d072704bd1ef7682044.

To me it looks like this functionality was never actually used. At least
I can't find any protection in vmw_bo_free().
