From 19d34d9aaf0c830dd9456731a7bb85b51670c1a7 Mon Sep 17 00:00:00 2001 From: "matti.halme@nokia.com" Date: Wed, 7 Jan 2009 09:10:07 +0200 Subject: [PATCH] Don't mask rtc-twl4030 alarm interrupts on shutdown A triggering RTC alarm should be able to power on a device that has been powered off. This patch enables that on twl4030 by not masking the alarm interrupt at shutdown.
