    This still beaks the probe deferral. :-(
    But that's another problem...

What does this 'MBR' mean? I am a novice~~~

   Generally speaking, Master Boot Record. But I also use it to send you My Best Regards. :-)

So, is it better to replace 'platform_get_irq' with
'platform_get_irq_optional' here?

   No. You should stop overriding the result to -ENOENT and pass the result
up the call chain instead. In order to do it, you should only check for (irq < 0).
