Subject: [ 43/85] cciss: fix incorrect scsi status reporting

From: Greg KH <gregkh@...uxfoundation.org>

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Stephen M. Cameron" <scameron@...rdog.cce.hp.com>

commit b0cf0b118c90477d1a6811f2cd2307f6a5578362 upstream.

Delete code which sets SCSI status incorrectly as it's already been set
correctly above this incorrect code.  The bug was introduced in 2009 by
commit b0e15f6db111 ("cciss: fix typo that causes scsi status to be
lost.")
