X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=809d9627087e1db63b8672c1f264af73b13116fb;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

drivers/rtc/rtc-efi.c: avoid subtracting day twice when computing year days

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.
