arcnet: fix signed bug in probe function
probe_irq_off() returns the first irq found or if two irqs are found then it returns the negative of the first irq found. We can cast dev->irq to an int so that the test for negative values works. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
