You are right. This is definitely not an error anymore.
What about
dev_warn(&pdev->dev, "unable to request IRQ, alarms disabled\n");
like some other drivers do?
grep -RHn 'unable to request IRQ, alarms disabled'
rtc-rv8803.c:576: dev_warn(&client->dev, "unable to request IRQ, alarms disabled\n");
rtc-m41t80.c:914: dev_warn(&client->dev, "unable to request IRQ, alarms disabled\n");
rtc-rv3028.c:651: dev_warn(&client->dev, "unable to request IRQ, alarms disabled\n");
rtc-pcf85363.c:416: dev_warn(&client->dev, "unable to request IRQ, alarms disabled\n");
rtc-pcf85063.c:458: "unable to request IRQ, alarms disabled\n");
rtc-rv3029c2.c:828: dev_warn(dev, "unable to request IRQ, alarms disabled\n");
rtc-rx8025.c:540: dev_err(&client->dev, "unable to request IRQ, alarms disabled\n");
rtc-abx80x.c:839: dev_err(&client->dev, "unable to request IRQ, alarms disabled\n");
