Hi, This series unifies the meaning of RTC_VL_READ by redefining it as a bitfield and defining the values of the various bits. This doesn't break compatibility with userspaceas long as the return value was used as a boolean, which should be the case. The series also ensures RTC_VL_CLR doesn't clear the information when it is about the data being invalid so the following rtc reads will properly fail.
