Can't the driver revert to single stage mode if platform_get_irq()
fails? That way the value of 'irq' can be tested throughout the
_probe() function and the #ifdefs removed.
I like that idea. The same can be done with the devm_request_irq()
call. It should definitely still display a warning if the command-line
option is set but no interrupt is available.
