-Subject: [PATCH] drm/vc4: Free hang state before destroying BO cache.
-
-The BO cache will complain if BOs are still allocated when we try to
-destroy it (since freeing those BOs would try to hit the cache).  You
-could hit this if you were to unload the module after a GPU hang.

-Fixes: 214613656b51 ("drm/vc4: Add an interface for capturing the GPU state after a hang.")
-(cherry picked from commit def96527707e1978a0c88e75d13b082f51460d5c)
