I like it, it's even more compact, I'll use it for next patch version.

Yes ... we're not yet there with pxa gpio interrupts, maybe it will come

A couple of lines below, using local "irqflags" variable :
       ret = devm_request_irq(&pdev->dev, cot->irq, lubbock_irq_handler,
                              irqflags, dev_name(&pdev->dev), cot);

Cheers.
