Matt Roper c7aca235aa drm/i915/gen9: Drop invalid WARN() during data rate calculation ... It's possible to have a non-zero plane mask and still wind up with a total data rate of zero. There are two cases where this can happen: * planes are active (from the KMS point of view), but are all fully clipped (positioned offscreen) * the only active plane on a CRTC is the cursor (which is handled independently and not counted into the general data rate computations These are both valid display setups (although unusual), so we need to drop the WARN().
