From 3499116b915e260b275c167a471e0e05bbe3f1d6 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 24 Jul 2013 15:05:20 -0700 Subject: PTP: 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 ptp class code to use the correct field.
