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_<PERMS> in the drivers 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 series does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes. This series includes about one third of the auto-converted drivers. The remaining patches will be submitted after the next commit window.
