[-- Attachment #1: mv643xx_eth-fix-of_irq_to_resource-error-check.patch --]
[-- Type: text/plain, Size: 1023 bytes --]

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()")
