From foo@baz Tue Jul 9 15:19:10 PDT 2013
Date: Tue, 09 Jul 2013 15:19:10 -0700
To: Greg KH <gregkh@linuxfoundation.org>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Subject: rtc: convert class code to use dev_groups
The dev_attrs field of struct class is going away soon, dev_groups
should be used instead. This converts the rtc class code to use the
correct field.
