Subject: [PATCH v1 00/25] lib, rtc: Print rtc_time via %pt[dt][rv]

Recently I have noticed too many users of struct rtc_time that printing
its content field by field.

In this series I introduce %pt[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.
