From b4f9fe12157a33351d0df78e925dcacd13252783 Mon Sep 17 00:00:00 2001 From: Len Brown Date: Thu, 11 Dec 2008 14:37:26 -0500 Subject: ACPI: move wmi, asus_acpi, toshiba_acpi to drivers/platform/x86 These are platform specific drivers that happen to use ACPI, while drivers/acpi/ is for code that implements ACPI itself.
