This has already been implemented by current code. The original code you modified only leaves alarm enable bit. You may misunderstand the code.

Ah.. sorry. I misunderstood when I was writing the commit message. It is not about the enable bits of each time entry. It is about the enable bit. However, as rtc->ops->set_alarm is not called when alarm->enabled is false, the patch becomes meaningless.
