[PATCH] RTC class: error checks
The rtc_is_valid_tm() routine needs to treat some of the fields it checks as
unsigned, to prevent wrongly accepting invalid rtc_time structs; this is the
same approach used elsewhere in the RTC code for such tests.
Conversely, rtc_proc_show() is missing one invalid-day-of-month test that
rtc_is_valid_tm() makes: there is no day zero.
