For consistency with the rest of the file it should look like this: info->rtc_dev = devm_rtc_device_register(dev_name(&pdev->dev), &pdev->dev, &tegra_rtc_ops, THIS_MODULE); With that fixed: Reviewed-by: Thierry Reding <thierry.reding@avionic-design.de>

And RTC is also an abbreviation. =) Thierry

Use devm_rtc_device_register for registering rtc device. This will reduce the code for unregistering rtc device in cleanup path and remove the implementation of remove callback of platform driver.
