It's simpler to just re-write it in a cleaner\nway.  The issues here are:\n\n1) If \"idxd->max_wqs\" is <= 0 then we call put_device(conf_dev) when\n   \"conf_dev\" hasn't been initialized.\n2) If kzalloc_node() fails then again \"conf_dev\" is invalid.  It's\n   either uninitialized or it points to the \"conf_dev\" from the\n   previous iteration so it leads to a double free.\n\nIt's better to free partial loop iterations within the loop and then\nthe unwinding at the end can handle whole loop iterations.  I also\nrenamed the labels to describe what the goto does and not where the goto\nwas located."
