From: Ville Syrjälä <[email protected]> skl_compute_plane_wm() doesn't actually need the plane state. While it would make logically sense to pass it, we shall need to reuse skl_compute_plane_wm() to compute the minimum ddb allocation for the cursor before the cursor may be enabled. Thus we can't rely on the plane state. The alternative would be to duplicate a lot of the wm calculations for the cursor ddb allocation case, which doens't appeal to me.
