Subject: [PATCH V5 07/12] ACPI: use platform bus as the default bus for _HID enumeration
Date: Tue, 8 Apr 2014 00:06:54 +0800 [thread overview]
Message-ID: <1396886819-2637-8-git-send-email-rui.zhang@intel.com> (raw)
In-Reply-To: <1396886819-2637-1-git-send-email-rui.zhang@intel.com>
Because of the growing demand for enumerating ACPI devices to platform bus,
this patch changes the code to enumerate ACPI devices with _HID to
platform bus by default, unless the device already has a scan handler attached.
