mv643xx_eth: fix of_irq_to_resource() error check
of_irq_to_resource() has recently been fixed to return negative error #'s along with 0 in case of failure, however the Marvell MV643xx Ethernet driver still only regards 0 as invalid IRQ -- fix it up. Fixes: 7a4228bbff76 ("of: irq: use of_irq_get() in of_irq_to_resource()") Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Signed-off-by: David S. Miller <davem@davemloft.net>
