Coccinelle reports a redundant error print in rb532_pata_driver_probe.
As 'platform_get_irq' already prints the error message, error print
here is redundant and can be removed.

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

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

Well, I didn't even notice this. It does seem to be another problem...

BTW, your patch summary looks quite wrong -- we need the prefix to specify the patch locus,
like this:
pata_rb532_cf: remove redundant error printing in the probe() method
I.e. "ata: " may even be omitted (your choise though).
