-Subject: rtc: cmos: ignore bogus century byte
-
-Older versions of Libreboot and Coreboot had an invalid value
-(`3' in my case) in the century byte affecting the GM45 in
-the Thinkpad X200.  Not everybody's updated their firmwares,
-and Linux <= 4.2 was able to read the RTC without problems,
-so workaround this by ignoring invalid values.

-Fixes: 3c217e51d8a272b9 ("rtc: cmos: century support")
