If you used ds1511_base, ioaddr in rtc_plat_data is not needed.

Still "noinline" here and there.

It would be better to use S_IWUSR instead of S_IWUGO. Please check
rtc-ds1553 changes in current git tree.

Use "rtc-ds1511" for driver name for hotplugging. Please check
rtc-ds1553 changes in current git tree.

Do not return void value. Please check rtc-ds1553 changes in current
git tree.
