[PATCH 19/21] drm/nouveau: wrap pm_runtime_* calls with nouveau_runpm
Ben Skeggs
bskeggs at nvidia.com
Thu Jun 13 17:00:11 UTC 2024
This wraps direct calls to pm_runtime functions to cleanup some common
usage patterns, and keep the logic in one place.
>From the next commit, the pm_runtime calls will need to operate against
the DRM driver's auxiliary device instead of directly on the underlying
PCI device. This commit will help make that switch cleaner.
