Please change this also instead of 'goto free_fence_drv' just return err.
fence_drv = kzalloc(sizeof(*fence_drv), GFP_KERNEL);
if (!fence_drv) {
DRM_ERROR("Failed to allocate memory for fence driver\n");
r = -ENOMEM;
goto free_fence_
The goto frees "fence_drv" so this is a double free bug. There is no
need to call amdgpu_seq64_free(adev, fence_drv->va) since the seq64
allocation failed so change the goto to goto free_fence_drv. Also
propagate the error code from amdgpu_seq64_alloc() instead of hard coding
it to -ENOMEM.
