Out of curiosity, when digging the nvif_driver for reviewing this
patch, I found:
static const struct nvif_driver *
nvif_driver[] = {
#ifdef __KERNEL__
&nvif_driver_nvkm,
#else
&nvif_driver_drm,
&nvif_driver_lib,
&nvif_driver_null,
#endif
Does nvif_driver_drm, nvif_driver_lib, nvif_driver_null still have
valid users nowadays in the userspace? Or should they also be removed in
this patch series?
