Summary

  • trtllm_mxint4_block_scale_moe writes results into the symm_output buffer passed via the output= kwarg. The return value is a list which CombinedOutput doesnt expect

`trtllm_mxint4_block_scale_moe` writes into the `symm_output` buffer
passed via the `output=` kwarg, but the return value was being captured
into a separate `output` variable and returned instead of `symm_output`.
