commit ebfd20a0a44b52d70d49945d6d077e907ca6a43a
Author: Zheng Bao <fishba...@gmail.com>

mc146818rtc: Update the Day of Week in CMOS in the right way.
The range of weekday in CMOS is 01-07, while the Sunday is 1, and
Saturday is 7. The comand date in coreutils defines
%u day of week (1..7); 1 is Monday
%w day of week (0..6); 0 is Sunday
There are 1 day offset for each week day. So we use "%w" and plus 1
before we update the weekday in CMOS.
