Subject: [PATCH 070] NCR53C9x unused SCp.have_data_in
Sender: linux-kernel-owner@vger.kernel.org
X-Mailing-List: linux-kernel@vger.kernel.org

NCR53C9x: Remove unused initialization of SCp.have_data_in (from Maciej W.
Rozycki). This affects the following drivers:
  - Amiga Oktagon SCSI
  - DECstation SCSI

The change for DECstation SCSI sneaked in through a MIPS update.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
