From ed52ccbce7ffdde51f116e2cc9de00251f1ff7c5 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Fri, 23 Jan 2015 09:01:10 -0500 Subject: [PATCH] asus-laptop: use DEVICE_ATTR_xx macros Use DEVICE_ATTR_{RO,WO,RW} macros to simplify sysfs attributes declaration. To declare a "foo" attribute, DEVICE_ATTR_RW() requires foo_show() and foo_store(), so rename a few functions to satisfy this requirement. Also put the macro below each related show/store functions for clarity.
