2019-02-18hwmon: (sht21) Use permission specific SENSOR[_DEVICE]_ATTR variantsGuenter Roeck
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. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2012-10-10hwmon: Add missing inclusions of <linux/jiffies.h>Jean Delvare
Many hwmon drivers use jiffies but omit the inclusion of the header file. Fix that, and also fix one driver which was including the header file but didn't need it.
