drivers/hid/wacom_sys.c:1796:8-16: WARNING: use scnprintf or sprintf
From Documentation/filesystems/sysfs.txt:
show() must not use snprintf() when formatting the value to be
returned to user space. If you can guarantee that an overflow
will never happen you can use sprintf() otherwise you must use
scnprintf().
