In the Linux kernel, the following vulnerability has been resolved:
i40e: fix IRQ freeing in i40e_vsi_request_irq_msix error path
If request_irq() in i40e_vsi_request_irq_msix() fails in an iteration
later than the first, the error path wants to free the IRQs requested
so far. However, it uses the wrong dev_id argument for free_irq(), so
it does not free the IRQs correctly and instead triggers the warning:
Trying to free already-free IRQ 173

Use the same dev_id for free_irq() as for request_irq().
I tested this with inserting code to fail intentionally.
