From 465ae641e4a3e5028aa9c85d3843259aa28a22ce Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sat, 11 Nov 2006 17:18:42 +1100 Subject: ACPI: Change ACPI to use dev_archdata instead of firmware_data Change ACPI to use dev_archdata instead of firmware_data This patch changes ACPI to use the new dev_archdata on i386, x86_64 and ia64 (is there any other arch using ACPI ?) to store it's acpi_handle. It also removes the firmware_data field from struct device as this was the only user.
