Hi folks, Currently, when the device is removed (or the driver is unbound) the nouveau_drm structure de-allocated. However, it's still accessible from and used by some DRM layer callbacks. For example, file handles can be closed after the device has been removed (physically or otherwise). This series converts the Nouveau device structure to be allocated and de-allocated with the devm_drm_dev_alloc() API. In the future, additional resources that should be bound to the lifetime of the drm_device can be added, and the drmm_add_action() APIs offer a nice hook for arbitrary cleanup actions before the drm_device is destroyed, so I suspect much of the current cleanup code in Nouveau would benefit from some refactoring to use this. Finally, although not *strictly* necessary for this series, I included some documentation for structures I investigated for this work.
