Subject: mlx5: memory leaks

Hi, Kernel Maintainers,

    In method mlx5_ib_destroy_gsi of gsi.c, there are memory leaks when ret = ib_destroy_qp(gsi->rx_qp); returns true? I think, ib_free_cq(gsi->cq); kfree(gsi->outstanding_wrs); kfree(gsi->tx_qps); should also be put before return ret before Line 180. If this is a real bug, I can send a patch. Thanks!
