The driver overrides the error codes and IRQ0 returned by platform_get_irq()
to -ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the error
codes upstream. IRQ0 is no longer returned by platform_get_irq(), so we now
can safely ignore it...
