From e1211e3fa7fd05ff0d4f597fd37e40de8acc6784 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sat, 1 Apr 2006 01:38:18 +0900 Subject: [PATCH] libata: implement ata_dev_enabled and disabled() This patch renames ata_dev_present() to ata_dev_enabled() and adds ata_dev_disabled(). This is to discern the state where a device is present but disabled from not-present state. This disctinction is necessary when configuring transfer mode because device selection timing must not be violated even if a device fails to configure.
