- 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.
- Signed-off-by: Eric Anholt <eric@anholt.net>
- Fixes: 214613656b51 ("drm/vc4: Add an interface for capturing the GPU state after a hang.")
- (cherry picked from commit def96527707e1978a0c88e75d13b082f51460d5c)
