Subject: [PATCH] ACPI: Do not pass NULL to acpi_get_handle() when looking for _EJD
Date: Thu, 14 Feb 2008 13:40:34 +0100 [thread overview]
Message-ID: <20080214124034.GA9708@homac.suse.de> (raw)
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.
