3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 809d9627087e1db63b8672c1f264af73b13116fb upstream.
Compared source code of rtc-lib.c::rtc_year_days() with
efirtc.c::rtc_year_days(), found the code in rtc-efi decreases value of
day twice when it computing year days. rtc-lib.c::rtc_year_days() has
already decrease days and return the year days from 0 to 365.
