From 3dba95dfd47d42b09193a24c3c6f74a9a1f8c004 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 22 Dec 2016 13:04:54 +0100 Subject: hwmon: (lm92) use permission-specific DEVICE_ATTR variants Use DEVICE_ATTR_RO for read-only 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.
