From b2ed508e94e5e90076b26f6a7661e559c516405e 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.
