3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Usyskin <alexander.usyskin@intel.com>
commit cfda2794b5afe7ce64ee9605c64bef0e56a48125 upstream.
function 'strncpy' will fill whole buffer 'id.name' of fixed size (32) with string value and will not leave place for NULL-terminator. Possible buffer boundaries violation in following string operations. Replace strncpy with strlcpy.
