From 0c88758b5a6325428aaadab619886242db20ceae Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 6 Aug 2007 18:36:23 +0900 Subject: [PATCH] libata-link: make two port flags HRST_TO_RESUME and SKIP_D2H_BSY link flags HRST_TO_RESUME and SKIP_D2H_BSY are link attributes. Move them to ata_link->flags. This will allow host and PMP links to have different attributes. ata_port_info->link_flags is added and used by LLDs to specify these flags during initialization.
