From 5fe7454aa9c6ef5fcf506b0f2dfc20f696891f1a Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 10 May 2010 21:41:37 +0200 Subject: [PATCH] libata-sff: ap->[last_]ctl are SFF specific ap->[last_]ctl are specific to SFF controllers. Put them inside CONFIG_ATA_SFF and move initialization into ata_sff_port_init().
