drm/i915: Fix pipe enabled mask for pipe C in WM calculations
Fix the incorrect enabled pipes mask for pipe C in the WM calculations. Additionally, in an effort to make the code easier to understand, populate the mask with 1 << PIPE_[ABC] instead of raw numbers. v2: Use 1 << PIPE_[ABC] (ickle/danvet) v3: Pass PIPE_[ABC] to g4x_compute_wm0() (ickle) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
