ACPI: Ignore _BQC object when registering backlight device
According to acpi spec , the objects of _BCL and _BCM are required if integrated LCD is present and supports brightness level .The _BQC is the optional object. So the _BQC object is ignored when the backlight device is registered in ACPI video driver. http://bugzilla.kernel.org/show_bug.cgi?id=10206 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
