From cc0680a580b5be81a1ca321b58f8e9b80b5c1052 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 6 Aug 2007 18:36:23 +0900 Subject: libata-link: linkify reset Make reset methods and related functions deal with ata_link instead of ata_port. * ata_do_reset() * ata_eh_reset() * all prereset/reset/postreset methods and related functions This patch introduces no behavior change.
