[patch 2.6.20-rc3] rtc-sa1100 correctly reports rtc_wkalrm.enabled

From: David Brownell
Date: Sat Jan 06 2007 - 01:49:41 EST


This fixes one bug in the SA-1100/PXA RTC support: read_alarm()
isn't reporting whether the alarm is enabled. This causes a small
regression, with procfs no longer reporting that state.

Note there are still bugs with how this driver handles this "enabled"
flag when it _sets_ alarms. I'm told the hh.org tree already merged
this particular patch.
