From f0d36efdc624beb3d9e29b9ab9e9537bf0f25d5b Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sat, 20 Jan 2007 16:00:28 +0900 Subject: libata: update libata core layer to use devres Update libata core layer to use devres. * ata_device_add() acquires all resources in managed mode. * ata_host is allocated as devres associated with ata_host_release. * Port attached status is handled as devres associated with ata_host_attach_release(). * Initialization failure and host removal is handedl by releasing devres group. * Except for ata_scsi_release() removal, LLD interface remains the same. Some functions use hacky is_managed test to support both managed and unmanaged devices. These will go away once all LLDs are updated to use devres.
