From ba949ed62dcd51ba2a514f9a7b6b7de252621536 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 10 Dec 2018 14:02:04 -0800 Subject: [PATCH] hwmon: (dell-smm-hwmon) Use permission specific SENSOR[_DEVICE]_ATTR variants MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readbility, and to reduce the chance of inconsistencies. Also replace any remaining S_ in the driver with octal values. The conversion was done automatically with coccinelle. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches/hwmon/. This patch does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes.
