hwmon: (stts751) Fix buffer size passed to snprintf
Function snprintf already cares for the terminating NUL at the end of the string, the caller doesn't need to do it. Signed-off-by: Jean Delvare <jdelvare@suse.de> Cc: Andrea Merello <andrea.merello@gmail.com> Cc: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
