[Mesa-dev] [PATCH] swr: [rasterizer core] don't attempt to load another RTAI when storing

[Ilia Mirkin]

Since we don't pass a renderTargetArrayIndex in, and the current hot
tile may be for a different index, we may end up loading the RTAI=0 into
the hot tile for no reason.

Noticed this when doing an audit of GetHotTile calls without a renderTargetArrayIndex being passed in. In this case, I don't think it should be loading at all...

Note that this has not been rigorously tested.
