From ad4beaccb0882af065befc18665f461d9711a2d4 Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Mon, 3 Sep 2012 20:50:30 +0200 Subject: SCSI: Fix incorrect memset in bnx2fc_parse_fcp_rsp commit 16da05b1158d1bcb31656e636a8736a663b1cf1f upstream. gcc 4.8 warns because the memset only clears sizeof(char *) bytes, not the whole buffer. Use the correct buffer size and clear the whole sense buffer. /backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c: In function 'bnx2fc_parse_fcp_rsp': /backup/lsrc/git/linux-lto-2.6/drivers/scsi/bnx2fc/bnx2fc_io.c:1810:41: warning: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to provide an explicit length?
