Subject: hwmon: (lm77) Use permission specific SENSOR[_DEVICE]_ATTR variants
X-Git-Tag: v5.4-rc1~1545^2~63
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=97b539d58204776e0f23c372415bd6f9df542d21;p=platform%2Fkernel%2Flinux-rpi.git

hwmon: (lm77) 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_<PERMS> 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.
