Subject: rtc: don't write RTC century when setting a wake alarm
From: Mark Lord <lkml@xxxxxx>
Fix /proc/acpi/alarm to not overwrite the RTC century field when setting a
wake alarm. The alarm hardware doesn't have a century field, and we really
should not be fiddling with the RTC century field here.
