drm/nouveau: store nvkm_device pointer in nouveau_drm
There's various different places in the drm code that get at the nvkm_device via various creative (and not very type-safe) means. One of those being via nvif_device.object.priv. Another patch series is going to entirely remove the ioctl-like interfaces beween the drm code and nvkm, and that field will no longer exist. This provides a safer replacement for accessing the nvkm_device, and will used more in upcoming patches to cleanup other cases. v2: - fixup printk macros to not oops if used before client ctor Signed-off-by: Ben Skeggs <bskeggs@nvidia.com> Signed-off-by: Danilo Krummrich <dakr@kernel.org> Link: https://patchwork.freedesktop.org/patch/msgid/20240726043828.58966-6-bskeggs@nvidia.com
