From 6b41013d6ee4e7fb63eddcc59be12032cf9c9bdb Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 22 Dec 2016 13:04:30 +0100 Subject: [PATCH] hwmon: (adm1021) use permission-specific DEVICE_ATTR variants Use DEVICE_ATTR_RO for read only attributes and DEVICE_ATTR_RW for read/write attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The conversion was done automatically using coccinelle. It was validated by compiling both the old and the new source code and comparing its text, data, and bss size.
