From 703d641d87034629f8b0da94334034ed5d805b36 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 18 Jan 2013 16:05:12 +0300 Subject: [PATCH] target: change sprintf to snprintf in transport_dump_vpd_ident "buf" is 128 characters and "vpd->device_identifier" is 256. It makes the static checkers complain. Also bump VPD_TMP_BUF_SIZE to match INQUIRY_VPD_DEVICE_IDENTIFIER_LEN.
