Subject: [PATCH] don't reset alarm interrupt on RTC
Date: Wed, 31 Oct 2001 14:08:41 -0800 [thread overview]
Message-ID: <3BE07669.5FF78E63@sun.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 339 bytes --]
All,
Attached is a 1-liner to not clear the Alarm-Int-Enable bit automatically
on the RTC device. This makes wake-on-alarm possible.
Please let me know if there is a problem with it. This is against 2.4.13
for inclusion in 2.4.14.
Tim
