From 7ecd9a3f062147400e605713724dd67dbb7e5053 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 10 Dec 2014 15:52:33 -0800 Subject: [PATCH] rtc: omap: fix missing wakealarm attribute The platform device must be registered as wakeup capable before registering the class device, or the wakealarm attribute will not be created. Also make sure to unregister the wakeup source on probe errors.
