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.

Yes, I agree with that too, brilliant idea, this will be in v11 patchset
