From c9f75b04ed5ed65a058d18a8a8dda50632a96de8 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 7 Apr 2008 22:47:21 +0900 Subject: [PATCH] libata: kill ata_noop_dev_select() Now that SFF assumptions are separated out from non-SFF reset sequence, port_ops->sff_dev_select() is no longer necessary for non-SFF controllers. Kill ata_noop_dev_select() and ->sff_dev_select initialization from base and other non-SFF port_ops.
