Subject: [PATCH] scsi: aic7xxx: Remove dead code
Date:   Sat, 24 Aug 2019 20:38:22 +0530
Message-Id: <1566659302-3514-1-git-send-email-jrdr.linux@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

These are dead code since 2.6.13. If there is no plan
to use it further, these can be removed forever.
