nice catch, many thanks.

However, this should also handle the case for sock->cb_irq being zero,
like it is done in yenta_close.
Furthermore, when comparing yenta_close and this error path in yenta_probe(),
I noticed a few other issues:
- yenta_free_resources() is not called in yenta_probe()
- pci_set_drvdata(dev, NULL) and kfree(socket) are not called in yenta_probe()
- sock->base is always set to non-NULL when yenta_close() is called,
therefore the check in yenta_close() may be removed.
Would you be willing to update your patch to address also these issues?
Then, I'll happily push it upstream.
