[Intel-gfx] [PATCH 03/35] drm/i915: Calculate the sprite WM based on the source width instead of the destination width

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Using the destination width in the sprite WM calculations isn't correct.
We should be using the source width.
