In this series I introduce %ptR[dt][rv] specifier to make life a bit easier. There are still users of detailed output of the struct rtc_time, but we can introduce an additional extension for them in the future if needed, otherwise they might be converted to the proposed output format. Some of the changes slightly modify the output. In those cases we are on the safe side since they are pure debug. Nevertheless I tried to leave numbers to be the same or quite close: in some cases year is printed + 1900, though month is left in the range [0,11] instead of [1,12]. I didn't compile everything there, though I did a basic smoke test on some x86 hardware. So, I rely on kbuild test robot as well :-) Most of the users currently are RTC drivers, thus the patch series is assumed to go via RTC tree. The patch series depends on earlier send clean up of lib/vsprintf [1].
