From 2b653e06ce2d70d21483f22ef1b1b63749c54223 Mon Sep 17 00:00:00 2001 From: Zhao Yakui Date: Tue, 15 Apr 2008 14:34:29 -0700 Subject: rtc: fix the error in the function of cmos_set_alarm There is a bug in the function of cmos_set_alarm. RTC alarm time for October can't be set correctly. For October: 0x0A will be written into the RTC region (MONTH_ALARM) in current kernel. But in fact 0x10 should be written. Wildcards are also not handled correctly.
