From 884b4aaaa242a2db8c8252796f0118164a680ab5 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Sun, 10 Dec 2006 02:19:00 -0800 Subject: [PATCH] rtc: Add rtc_merge_alarm() Add rtc_merge_alarm(), which can be used by rtc drivers to turn a partially specified alarm expiry (i.e. most significant fields set to -1, as with the RTC_ALM_SET ioctl()) into a fully specified expiry. If the most significant specified field is earlier than the current time, the least significant unspecified field is incremented.
