fwnode_irq_get() was changed to not return 0 anymore.

Drop check for return value 0.

...

-    if (data->irqnr <= 0) {
+    if (data->irqnr < 0) {
          /* usage of interrupt is optional */
          data->irqnr = -1;
      } else {


After this change I'm not sure we need this branch at all, I mean that -errn is equal to -1 in the code (but needs to be checked for silly checks like == -1).

Hence

Entire excerpt can be replaced with

    if (data->irqnr > 0) {


I agree. Furthermore, at a quick glance it seems the whole irqnr could be dropped from the private data, and the private data struct could probably be static. I'd send them as separate clean-ups though as those changes are not really related to this return-value series.

Please, ignore everything I wrote above, except that I agree to your suggestion. I was writing utter nonsense. Sorry for the noise.


Yours,
