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...
