From 4f5e2f38f4377aa609dfe397ab2c9775897430c7 Mon Sep 17 00:00:00 2001 From: Varun Prakash Date: Fri, 5 Apr 2019 20:39:13 +0530 Subject: [PATCH] scsi: csiostor: fix missing data copy in csio_scsi_err_handler() [ Upstream commit 5c2442fd78998af60e13aba506d103f7f43f8701 ] If scsi cmd sglist is not suitable for DDP then csiostor driver uses preallocated buffers for DDP, because of this data copy is required from DDP buffer to scsi cmd sglist before calling ->scsi_done().
