On a request_irq() failure the cleanup loop\n\"for (j = 0; j \u003c i; j++)\" frees msix_entries[j].vector but passes the\nfailed index's \u0026card-\u003emsix_ctx[i] as the dev_id. free_irq() matches on\n(irq, dev_id), so it fails to find the action registered with\n\u0026card-\u003emsix_ctx[j]: the already-requested IRQ j is not freed (leaked) and\nfree_irq() warns about freeing a non-existent IRQ.
