From 270390e1ae1818b111543b8bfffa08095d73c1a5 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 10 May 2010 21:41:35 +0200 Subject: libata-sff: introduce ata_sff_init/exit() and ata_sff_port_init() In preparation of proper SFF/BMDMA separation, introduce ata_sff_init/exit() and ata_sff_port_init(). These functions currently don't do anything.
