For two reasons: - The driver core clears this already for us after we're unloaded in __device_release_driver(). - It's way too late, the drm_device ->release callback might massively outlive the underlying physical device, since a drm_device can't be kept alive by open drm_file or well really anything else userspace is still hanging onto. So if we clear this ourselves, we should clear it in the pci ->remove callback, not in the drm_device ->relase callback.
