OK, I see.

I just look at other devm_* API. All devm_* APIs use 'struct device*'
as first argument.

To prevent the confusion, I will send the patch that uses
'struct device*' as first argument as below.

 struct rtc_device *devm_rtc_device_register(struct device *dev,
                                         const char *name,

Thanks for your comment
