From: bui duc phuc irq_of_parse_and_map() returns 0 when parsing or mapping an IRQ fails. The current condition also checks for negative values, even though irq_of_parse_and_map() does not return negative error codes. Check only for a zero return value to match the semantics of irq_of_parse_and_map().
