From d6b0de8c28ef32d081cfee938e443ce2a2429cfe Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 19 May 2010 22:10:23 +0200 Subject: libata-sff: kill dummy BMDMA ops from sata_qstor and pata_octeon_cf Now that SFF and BMDMA are completely separate, sata_qstor and pata_octeon_cf which inherit from ata_sff_port_ops don't need to worry about BMDMA ops being called. Kill the dummy BMDMA ops.
