From d43ec68e9837dfa6618ab473622683fdbf6e68a9 Mon Sep 17 00:00:00 2001 From: Patrick Mochel Date: Thu, 7 Dec 2006 20:56:23 +0800 Subject: [PATCH] ACPI: add device_driver and hepler functions Add device_driver into acpi_driver for driver model. Add helper functions 'to_acpi_device' and 'to_acpi_driver' to get structure acpi_device/acpi_driver by device/device_driver.
