From 3130451e270960065e8de684c60b898e970c940c Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Wed, 14 Feb 2018 17:43:16 +0200 Subject: x86/platform/atom: Re-use DEFINE_SHOW_ATTRIBUTE() macro ...instead of open coding file operations followed by custom ->open() callbacks per each attribute. While here, replace permissions by explicit octal value.
