Documentation: hwmon: Add descriptions for ina2xx sysfs entries
There are a few sysfs entries being exposed to user space by the ina2xx hwmon driver while not getting explicitly documented. So this patch just adds a description section for them. Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
