Subject: wlan: Replace snprintf with scnprintf
The function snprintf() do not write more than size bytes (including
the terminating null byte ('\0')). If the output was truncated due
to this limit then the return value is the number of characters
(excluding the terminating null byte) which would have been written
to the final string if enough space had been available. Thus, a
return value of size or more means that the output was truncated.
