The driver neglects to check the result of platform_get_irq()'s call and
blithely passes the negative error codes to devm_request_threaded_irq()
(which takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding
an original error code. Stop calling devm_request_threaded_irq() with the
invalid IRQ #s.

let's avoid multiple assignments in one line. How about:
if (udc->udp_irq < 0) {
retval = udc->udp_irq;
goto err_unprepare_iclk;
}

Oops, duplicate patch. Scratch the series, I'm going to restart posting tomorrow... :-)
