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. Only build-tested on x86 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Len Brown <lenb@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
