On a request_irq() failure the cleanup loop\n\"for (j = 0; j < i; j++)\" frees msix_entries[j].vector but passes the\nfailed index's &card->msix_ctx[i] as the dev_id. free_irq() matches on\n(irq, dev_id), so it fails to find the action registered with\n&card->msix_ctx[j]: the already-requested IRQ j is not freed (leaked) and\nfree_irq() warns about freeing a non-existent IRQ. Use &card->msix_ctx[j]."
