From 9da01759636f519967c0922ae12bd9fff739db9a Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 24 Jul 2013 15:05:39 -0700 Subject: [PATCH] pwm: 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 PWM class code to use the correct field.
