Subject: [PATCH] tools/power turbostat: Fix gcc build warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit d8d005ba6afa502ca37ced5782f672c4d2fc1515 upstream.

Warning: ‘__builtin_strncpy’ specified bound 20 equals destination size
	[-Wstringop-truncation]

reduce param to strncpy, to guarantee that a null byte is always copied
into destination buffer.
