Subject: drm/nouveau/core/client: use standard object dtor/init/fini paths
X-Git-Tag: Ubuntu-5.13.0-19.19~13983^2~12^2~43
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=2c3af924fbee23544a6adc81a2bbe398132b472f;p=mirror_ubuntu-jammy-kernel.git

drm/nouveau/core/client: use standard object dtor/init/fini paths

Preparation for supporting subclients, and also good for consistency.
