From 3b5fee5952ff7eb6ff7a64247a01040b8b331b74 Mon Sep 17 00:00:00 2001 From: Holger Macht Date: Thu, 14 Feb 2008 13:40:34 +0100 Subject: [PATCH] ACPI: Do not pass NULL to acpi_get_handle() when looking for _EJD When trying to get the acpi_handle from an acpi_buffer, pass ACPI_ROOT_OBJECT instead of NULL to acpi_get_handle(). This fixes the detection of dock dependent bays.
