> Subject: [Intel-wired-lan] [PATCH net v2] idpf: Fix mailbox IRQ name
> leak on request failure
>
> idpf_mb_intr_req_irq() allocates the mailbox IRQ name before calling
> request_irq(). On success, the name is released later through
> kfree(free_irq()), but request_irq() failure returns without freeing
> it.
>
> Free the allocated name on the request_irq() failure path.
