The driver's probe() method is written as if platform_get_irq() returns 0
on error, while actually it returns a negative error code (with all the
other values considered valid IRQs).  Rewrite the driver's IRQ checking
code to pass the positive IRQ #s to request_irq() and use polling mode
when platform_get_irq() returns negative error code (or IRQ0)...
