From a9283c8fe9a1022f503ccb044a759519e7d43ff4 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Mon, 10 Dec 2018 14:02:12 -0800 Subject: [PATCH] hwmon: (lm83) Use permission specific SENSOR[_DEVICE]_ATTR variants Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readability, 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.
