tracing: Don't use the address of the buffer array name in copy_from_user
With the following code snippet: ... char buf[64]; ... if (copy_from_user(&buf, ubuf, cnt)) ... Even though the value of "&buf" equals "buf", but there is no need to get the address of the "buf" again. Use "buf" instead of "&buf".
