[PATCH] don't reset alarm interrupt on RTC

[Tim Hockin <thockin@sun.com>]

[-- 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.
