Subject: [PATCH 33/36] net: rfkill: convert class code to use dev_groups
Date: Wed, 24 Jul 2013 15:05:36 -0700	[thread overview]
Message-ID: <1374703539-9705-34-git-send-email-gregkh@linuxfoundation.org> (raw)
In-Reply-To: <1374703539-9705-1-git-send-email-gregkh@linuxfoundation.org>

The dev_attrs field of struct class is going away soon, dev_groups
should be used instead.  This converts the rfkill class code to use the
correct field.
