Pushed.

>   drm/i915/display: Make WARN* drm specific where drm_device ptr is available
>   drm/i915/display: Make WARN* drm specific where drm_priv ptr is available

The above two conflict and need to be rebased.

>   drm/i915/display: Make WARN* drm specific where encoder ptr is available
>   drm/i915/gem: Make WARN* drm specific where drm_priv ptr is available
>   drm/i915/gt: Make WARN* drm specific where drm_priv ptr is available

Pushed the above three.

>   drm/i915/gvt: Make WARN* drm specific where drm_priv ptr is available
>   drm/i915/gvt: Make WARN* drm specific where vgpu ptr is available

The gvt patches need to be applied through the gvt tree and maintainers
once they've backmerged the logging changes.

>   drm/i915: Make WARN* drm specific where drm_priv ptr is available
>   drm/i915: Make WARN* drm specific where uncore or stream ptr is available

Pushed the above two.

Thanks for the patches.

BR,
Jani.
