From 4390ce002b02f3ddea2dcd1850a45b332dfd8792 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Wed, 10 Dec 2014 15:52:43 -0800 Subject: [PATCH] rtc: omap: fix class-device registration Make sure not to register the class device until after the device has been configured. Currently, the device is not fully configured (e.g. 24-hour mode) when the class device is registered, something which involves driver callbacks for example to read the current time.
