[PATCH 6/9] drm/i915: Use enum plane_id in VLV/CHV sprite code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Use intel_plane->id to derive the VLV/CHV sprite register offsets
instead of abusing plane->plane which is really meant to for
primary planes only.
