From 76c8ae4b2fbcbc92601c48e1b534c35638c8d597 Mon Sep 17 00:00:00 2001 From: Santosh Nayak Date: Tue, 6 Mar 2012 22:36:59 +0530 Subject: [PATCH] [SCSI] bfa: Fix endian bug in bfad_iocmd_debug_fw_core(). Casting pointer from native data type to other type is endian-sensitive. "iocmd->offset" is 64 bit but we use only first 32 bit. It works in little-endian system but in big-endian system it will break.
