From de50ada55b6b83b54b817911ec42dc590e1c1738 Mon Sep 17 00:00:00 2001 From: Holger Macht Date: Mon, 25 Jun 2012 16:13:02 +0800 Subject: [SCSI] add wrapper to access and set scsi_bus_type in struct acpi_bus_type For being able to bind ata devices against acpi devices, scsi_bus_type needs to be set as bus in struct acpi_bus_type. So add wrapper to scsi_lib to accomplish that.
