From 5d9464a46918ced087c351a10f38cee95725f85b Mon Sep 17 00:00:00 2001 From: Patrick Mochel Date: Thu, 7 Dec 2006 20:56:27 +0800 Subject: ACPI: add ACPI bus_type for driver model Add ACPI bus_type for Linux driver model. 1. .shutdown method is added into acpi_driver.ops needed by bus_type operations. 2. remove useless parameter 'int state' in .resume method. 3. change parameter 'int state' to 'pm_message_t state' in .suspend method. Note: The new .uevent method mark ACPI drivers by PNPID instead of by name. Udev script needs to look for "HWID=" or "COMPTID=" to load ACPI drivers as a result.
