Subject: [PATCH AUTOSEL 5.4 11/19] tools/power turbostat: Fix gcc build warnings
Date: Thu, 26 Mar 2020 19:24:23 -0400	[thread overview]
Message-ID: <20200326232431.7816-11-sashal@kernel.org> (raw)
In-Reply-To: <20200326232431.7816-1-sashal@kernel.org>

From: Len Brown <len.brown@intel.com>

[ Upstream commit d8d005ba6afa502ca37ced5782f672c4d2fc1515 ]

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.
